Now we’re going to discuss a new type of organic mechanism called addition. There’s tons of these to keep track of, so let’s get right into it!

Addition reactions are ones in which 1 π-bond is broken and 2 new σ-bonds are formed.
They are the opposite of elimination reactions (if you haven’t learned about these yet don’t worry).
Example #1: Provide the mechanism for the following addition reaction.
