Which of the following will be least reactive towards nucleophilic substitution reaction?
Dear Student,
(b) will be least reactive towards nucleophilic substitution reaction. This is because, here the Cl atom is bonded to sp2 hybridised carbon atom and so it difficult to break the C-Cl bond. Also the carbocation formed will be destabilised by the -CH3 group, and so its rate of reaction will be least.
