How To Calculate Formal Charge To calculate the formal charge of an atom, we start by: evaluating the number of valence electrons (VE) the neutral
Read moreThe 4 Major Classes of Reactions in Org 1
At least 80% of the reactions you will learn in Org 1 fall into one of these 4 categories. The sooner you can get into the habit of recognizing bond formation and breakage the better off you will be.
Read moreThe Four Intermolecular Forces and How They Affect Boiling Points
Properties like melting and boiling points are a measure of how strong the attractive forces are between individual atoms or molecules. (We call these intermolecular
Read more3 Trends That Affect Boiling Points
Figuring out the order of boiling points is all about understanding trends. The key thing to consider here is that boiling points reflect the strength
