Homework Answers
Correct option: B
The leaving group -Br in option A and C is attached to the more sterically crowded tertiary and secondary carbon respectively. Hence, in these cases, the SN2 attack hindered by the steric factor. Halobenzenes (e.g bromobenzene in option D) never undergo SN2 reaction. The correct option is B which is a primary alkyl bromide.
