Which of the following is least reactive in a nucleophilic substitution reaction?

Multiple Choice Options

A $(CH_3)_3C-Cl$
B $CH_2=CHCl$
C $CH_3CH_2Cl$
D $CH_2=CHCH_2Cl$

Step-by-Step Verified Solution

Chlorine of vinyl chloride (CH 2 ==CHCl) is non-reactive substitution reaction because it shows the following resonating structure due to +M effect of �Cl atom. In second Cl�atom has positive charge and partial double bond character with C of vinyl group, so it is more tightly attracted towards the nucleus and it does not get replaced by nucleophile in nucleophilic substitution reaction.
