### Substitution Reactions

What is a substitution reaction and will we have to know it for the final?

### Re: Substitution Reactions

A substitution reaction occurs when an atom (or group of atoms) is replaced by another atom (or group of atoms). This kind of reaction is common in organic molecules with a leaving group and a nucleophile that replaces the leaving group in the reaction. Because Dr. Lavelle went over it in class, I would assume it is a good thing to know just in case it comes up as part of one of the questions on the final.

### Re: Substitution Reactions

What do we have to know about the Sn2 organic reaction substitution nucleophile 2? I get that an atom is replaced by another, but what is the nucleophile?
