According to the following energy profile, the rate of reaction from A to B is determined by:
The energy of B only.
The energy difference between C and A.
The energy of A only.
The energy difference between B and A.
Reaction of a bulky base such as (CH3)3CO– K⁺ with secondary alkyl halides gives predominantly E2 elimination rather than SN2 substitution because the transition state for SN2 reaction is more sterically hindered than that for E2 reaction.
