Sn1,2 / E1,2

[laundry]

Advertisement - Members don't see this ad

SN1:
- Polar protic solvent
- Bulky nucleophiles
- Weak bases

E1:
- Same as SN1, but preffered at higher temperatures

SN2:
- Polar aprotic solvent
- Less substitution
- Weaker base than E2

E2:
- Strong base (strong enough to remove a H)


anything else?

ive got a question regarding the E1 and E2. So on something like this reaction

2-chlorobutane 1. (CH3)3CO-Na+ 2. (CH3)3COH would give you 1-butene.

the base is bulky and is a secondary halide which would make it good for E2, but for E2, you need a polar Aprotic solvent, in this case we have a tertiary alcohol as the solvent, which is polar protic...can someone explain this discrepency??

I've been noticing this a lot

if you google this, you'll find really good/clear charts that list all the differences right next to each other. additionally, its in the back of the destroyer orgo in the solution section somewhere.

get the DAT destreyer and there is a full review of these important mechanisms. the info covered will help you to aswer ur qustion and other orgo questions. get it and you wan't regret it, promise.
