Which of the following alkyl halides is hydrolysed by SN2 mechanism? (BVP 2011) (a) C H CH Br (b) CH Br (c) CH CHCH Br

Answer

Explanation

SN2 mechanism involves the back side attack and formation of a transition state, thus less hindered alkyl halide readily undergoes SN2 mechanism. Among the given, 3 CH Br (methyl bromide) is less hindered, thus it is hydrolysed by SN2 mechanism.
