But if you're real hindered and your nucleophile is bad, Then SN1 will go (sometimes heat you must add) Eliminations are great if you want an alkene But make sure there's a leaving group and base on the scene.

Unformatted text preview: E2 likes tertiary and really strong bases, With double bonds forming in more substituted places. E1 makes a carbocation- weak bases are the clue But be careful! You can usually get SN1 too! And then, of course, we study addition Adding halogens or alcohols- depending on the condition. These can be done with alkenes or alkynes, Know the mechanisms well, and you will be fine. Pi bonds attack electrophiles is how we begin, Remember Markovnikov and anti or syn! Knowing all these reactions is great, but it isn't enough Put all the reactions together, and synthesize some stuff!...
