Answer 1

Answer #1

SN2 reactions involves Nucleophilic substitution reaction in which bond making and bond breaking take place simultaneously. The attack of nucleophile take place from backside to minimize steric hinderance.

To minimize steric hinderance, a halide which is least substituted i.e. primary halide will go via SN2 mechanism.

Сн, # on — Ти - - - Вх BY И, с си, - --- - - - - и о сна

Has steric hindered transition state. Hence will be less stable. So will give less product.

СМ» ги, о Эр-- ар -и -- Qт T Br и и Ти и

Less steric hindered transition state that's why give fast reaction as compared to above halide.
