How The MOC Membership Can Help You: 3000+ Practice Quiz Questions

On MOC, we have over 400 free articles on a huge number of topics in introductory organic chemistry that will help you think through these types of questions.

However, reading articles and memorizing facts is not enough to get an outstanding grade in an organic chemistry class.

As you’re probably aware, organic chemistry isn’t tested like biology. In organic chemistry, success depends not on being able to recall information, but to apply it.

The true key to understanding is to do a lot of practice problems.

Common Problems Students Encounter:

  • Learning a vast number of reactions and their mechanisms.
  • Understanding if reactions proceed through SN1/SN2/E1/E2 pathways
  • Identifying pairs of molecules as enantiomers, diastereomers, or constitutional isomers
  • Classifying molecules as aromatic or nonaromatic, and identifying substitutents as ortho- para- or meta– directors
  • Doing multi-step synthesis questions

The resources included in the MOC membership were designed to help you with all these problems and more.

I’ve gone through hundreds of individual midterms and exams and pulled out the most commonly covered types of questions over a two-semester organic chemistry course and built quizzes around these questions.

As a MOC member, you’ll have access to over 3000 practice quizzes spread over 30 sections that cover the most important concepts in each chapter. Including lots of commonly used “trick” questions.

After all, if you’ve seen the trick question before, it’s no longer a trick!

Our quizzes let you test your knowledge and give you instant feedback on whether you’re on the right track. This is much more than you’d get from just reading an article.

Reaction and Mechanism Guide

Organic chemistry courses are famous (infamous?!) for expecting you to learn a lot of reactions and mechanisms.

To prepare for the ACS exam, for example, it’s not unusual to be responsible for knowing over 130 different reactions and their mechanisms, and being able to apply the pattern of bonds that form and break to molecules you haven’t seen before.

There’s a lot to learn!

When you join the MOC membership you get access to our Reaction and Mechanism Encyclopedia with detailed individual pages on over 200 reactions in introductory organic chemistry along with mechanisms, examples, and quiz questions.

A few examples that are open-access to everyone, just to give you an idea:

For more, see the Reaction + Mechanism Guide page.

Printable, Ready-Made Reaction Flashcards

Some students find that making flashcards helps them learn reactions.

If you’re one of those people, you might like our downloadable (PDF) full-color printable flashcards, which are included with your MOC membership.

You can print out our ready-made flashcards and easily glue them onto conventional index cards.

Each flashcard contains a link to the mechanism (from the Reaction and Mechanism guide) on the back of each card.

Summary Sheets – Org 1, Org 2, and Spectroscopy

One of the main challenges with organic chemistry is trying to deal with the huge amount of information that’s thrown at you. With textbooks being over 1200 pages or longer, it can be tough to sort out the key concepts and facts you really need to understand.

Instructors often suggest making your own “cheat sheets” or “summary sheets” that summarize the key information you need on a few sheets of paper.

This will give you increased confidence, improved organization, better retention, and an increased ability to identify key patterns.

If you have the dedication to make these sheets for yourself, I encourage you to do it!

But just in case your other courses get in your way, we’ve got you covered.

Signing up for the MOC membership gives you access to 3 packs of organic chemistry summary sheets (PDFs) designed to summarize the key concepts from first-semester organic chemistry, second-semester organic chemistry, and a special unit on spectroscopy.

Org 1 Summary Sheets PDF – a 20 page PDF containing summaries on the following topics: Bonding & Hybridization • Formal Charge, Boiling Points, Curved Arrows • Alkane Nomenclature • Conformations and Newman Projections • Cycloalkanes • Resonance • Free Radicals • Acids and Bases • Substitution and Elimination • SN1/SN2/E1/E2 Decision • Alkene Reactions • Alkyne Reactions • Alcohols • Introduction to Synthesis

Org 2 Summary Sheets PDF – a 20 page PDF containing summaries on the following topics: Alcohols and Ethers • Reactions of Dienes • Molecular Orbitals • Diels-Alder Reactions • Aromaticity • Reactions of Aromatic Compounds • Aldehydes and Ketones • Carboxylic Acid Derivatives • Organometallics • Enols and Enolates • Amines • Carbohydrates • Amino Acids

Spectroscopy Pack PDF – a 15-page PDF containing summaries on: UV-Vis Spectroscopy • Mass Spectrometry • IR Spectroscopy • 1H NMR • 13C NMR • Problem Solving

Hundreds of hours went into the preparation of these premium study materials. Sold separately on our online store, these are a $50 value.

MOC Membership Has Helped Thousands of Students Succeed In Organic Chemistry

(And Can Help You Too!)

Here’s what some of our members have to say about the benefits of MOC membership.

 
Matt T.Colorado State University
I wish I would have made the move on your joining your site earlier in the semester. It would have made things a little bit easier. I joined about 2 weeks before finals and ended up getting an A in the class!
Tara R.Tara Rochford Nutrition
You helped me complete all the necessary courses and steps to become a registered dietitian. I can't thank you enough for your helpful guides for Organic Chemistry. You allowed me to pass the class and actually feel like I understood what was going on during the final.
Callie O.Augusta University
Thank you so much for such an awesome site! You're the reason I got an A in ochem one and two! Thank you!
Anna E.Wilkes University
I struggled with individual reactions, especially exceptions and anomalies, seeing as my professor only taught a brief overview of most reactions, and the great detail put into every reaction in the reaction guide helped me achieve great grades in a class where the majority was not passing.
JadeDurham University
My textbook made all mechanisms seem scary and complicated but the reaction guide is very well organised, making the reactions easy to understand. I love how for each reaction it is clear which bonds are broken and formed!
Julian D.University of Nebraska
Initially I was having an extremely difficult time understanding the background to a reaction. I could memorize the reaction, but I wanted to know the intricate details. This guide helped me understand the reaction in a more down to Earth way when compared to my textbook. I went from a C to an A- in Organic 1 and acing Organic 2 with an At.
Abbi M.Lee University
I made an A in my Organic 2 class - your website was an invaluable resource!! Thanks so much.
Kathleen N.City College, CUNY
The Reaction Guide was my key resource for exams. The concise, consistent format for each and every reaction I needed meant | could memorize reactions and spit them out on exams automatically. It worked, I surprised myself and got an A in Org 1.
R.P.SUNY. New Paltz
The ACS exam seemed impossible to tackle because I was struggling to master all the reactions and mechanisms, but the detailed explanations offered in the Reaction Guide helped me prepare in the weeks leading up to the exam, and finally, to earn the grade.
Leif F.Eckerd College
As final exams were approaching and my studying began, I had realized that I had a lot of notes to flip back to while doing practice problems. This website served as a great resource by keeping things quick and concise while also including all of the pertinent information included. I have recommended this resource to many of my peers because I truly believe that it helps.
Emma P.Salem State University
I was struggling a lot with orgo Emma P. Salem State University 1, particularly towards the end of the semester with how to study reactions. I wish I had found this resource at the beginning of the semester because I would've done so much better! In the end, I know this resource was a major contributor to me doing well on my final exam. I would've ended up with a C- in the course, but I did so well on the final thanks to this study guide, it brought me up a full letter grade. Definitely worth the investment!
Lori K.Johns Hopkins University
I was struggling with keeping track of all the reagents and mechanisms that are taught in the second semester of my Organic Chemistry course however the Reaction Guide helped me raise up my grade from a B to A.
Courtney E.Valdosta State Univeristy
I couldn't follow along with mechanisms in class to save my life, but this reaction guide was AMAZING. This is the clearest set explanations with I was struggling with keeping track of all the reagents and mechanisms that are taught in the second semester of my Organic Chemistry course diagrams I could find. There is no better reference material out there.
Amelia A.Duke University
I was struggling with keeping track of all the reagents and mechanisms that are taught in the second semester of my Organic Chemistry course however the Reaction Guide helped me raise up my grade from a B to A.
Ami YangUBC
I was struggling with retrosynthesis questions, the Reaction Guide helped me walked through this and I understand it now.
Casey S.YSU
I was having a really hard time understanding Nitrogen chemistry and there was a whole section of amines and amides to help me work through it. Instead of flooding me with tons of information it supplied the very important points that helped drive the reactions
Rich A.Temple University
The Reaction Guide is essential to any Organic student; James' specific notes for each mechanism are very helpful, and of course having a detailed reaction/mechanism encyclopedia at your fingertips saves countless hours of searching and verifying. Not to mention James' approach is friendly, genuine, and inspires confidence that he will help in any way possible and is receptive to feedback and suggestions. This is the resource I've been searching for all semester.
Sam Y.Bucks County Community College
I am in organic Il right now. Often when I am studying I need to be able to find a specific reaction mechanism or some information on reaction that explains it better. I usually dont want to have to open the text book and sort through several pages to find what I need. The reaction guide make that information easy to find quickly.
Rhiannon S.Cal Poly San Luis Obispo
I was struggling with understanding mechanisms and being able to have a place to look them up quickly helped me.
Tiana D.MiraCosta College
I was feeling bombarded with all the reactions I needed to learn, and this Reaction Guide helped me to feel less stressed. It is succinct and organized! Thank you!
Robin F.UNCP
I was struggling to keep up with reaction mechanisms, specifically which bonds were broken and which were formed. The reaction guide maps out exactly how the bonds change....this helped me tremendously! Now I can follow mechanisms from start to finish without getting lost.
Collin D.PSU
I was looking for a general guide to the various reactions encounter in org 1/2, and found that the reaction guide is extremely helpful whenever I can't remember where an arrow ought to go.
Joseph D.LSU Honors College
I had so much trouble finding online help that didn't over complicate basic answers to what I was confused about. The Reaction Guide actually put reactions in terms an organic noob can understand, making them feel like a master after no time at all. It was an invaluable tool during finals week. So concise and organized.
Eric G.University of New Hampshire
In my senior year I took advanced organic after already taken orgo 1 and 2, and I was having a pretty rough time getting by. Before I used the Reaction Guide, I would spend countless amounts of hours just sifting through my notes trying to find a specific reaction and sometimes, the mechanism would be slightly off and I would lose credit. The reaction guide provided an extensive list of common reactions that allowed me double check my notes and answers to. This guide cut down a lot of wasted time and subsequently boosted all of my exam scores.
Camie P.Idaho State
Studying for finals was making me eye twitching crazy. My prof was big on retro synthesis and I needed help. The clear explanations made understanding the reactions and thereby understanding how to make it a life saver. WORTH THE MONEY..!
Julie B.TCD
I was having a lot of problems understanding reaction mechanisms for lab reports and exam questions, but the reaction guide broke everything down into really simple steps and I find myself understanding things never thought would

Yes! This was actually designed for helping students with the ACS exams.  One of the students I was tutoring needed to learn 130 reaction mechanisms for her ACS exam, and since Wikipedia was of very uneven quality for introductory organic chemistry students, the logical solution was to build a dedicated mini-Wikipedia just for reactions and mechanisms that helped to walk students through each reaction.
