Question

Does E2 reaction proceeds with

3°>2°>1° or

1°>2°>3° of alkyl halide.And what's the reason for it?

Answer 1

E2 reaction proceeds with

3°>2°>1°

reason :-. In the transition state, the double bond is partially formed, so increasing the stability of the double bond with alkyl substituents stabilizes the transition state. so 3° is more reactive
