E2

Question 1

Do you use SN1, SN2, E1, or E2 with an alkyl halide reacting with a strong base?

Answer 1

E2

Question 2

What is the beta that is the fastest to abstract in E2?

Answer 2

The one that is anticoplanar to the LG

Question 3

SN1/E1 vs SN2/E2

Answer 3

SN1/E1: LG leaves to create carbocation & then nucleophile/base acts
SN2: LG leaves at the same time as nucleophile attacks
E2: LG leaves at the same time the base abstracts the beta-H bond

Question 4

When does the B-H need to be anticoplanar to the LG?

Answer 4

For E2 but not for E1 bc there is no halide in the step forming the pi
