Introduction to Nucleophilic Substitution Reactions
Following up on the 4 most important patters of reactions in Org 1, and introduction to acid-base reactions, here’s the second major pattern. It’s called

Introduction to Nucleophilic Substitution Reactions Today starts a new series of posts on walking through one of the key classes of reaction in organic chemistry:
Read moreTwo Types of Nucleophilic Substitution Reactions
Comparing Two Nucleophilic Substitution Reactions That Clearly Have Different Mechanisms Chemistry is an experimental science. There is no great Ramanujan of our discipline, who, starting
Read moreThe SN1 Mechanism
The SN1 Reaction Mechanism There are two important classes of nucleophilic substitution mechanisms – the SN1 and SN2 mechanisms (See article – Two Types of
Read moreThe Conjugate Acid Is A Better Leaving Group
Adding Acid Increases Leaving Group Ability Sure, it’s one thing to recognize halogens (Cl, Br, and I) as having high leaving group ability, as well
Read moreComparing the SN1 and SN2 Reactions
Comparing the SN1 and SN2 Reactions In nucleophilic substitution reactions, a bond between carbon and a leaving group (C–LG) is broken, and a new bond
Read moreThe SN1, E1, and Alkene Addition Reactions All Pass Through A Carbocation Intermediate
The Carbocation Intermediate That Connects The SN1, E1, And Alkene Addition Reactions Was going to include this in my last post but it was getting
Read moreWhat makes a good leaving group?
Good Leaving Groups Are Weak Bases A leaving group (a.k.a. “nucleofuge”) is the new Lewis base that is generated in various substitution and elimination reactions when
