Question

Arrange the following in decreasing order of their reactivity towards nucleophile: underset(. I .) textBenzoyl chloride underset(II) textBenzyl chloride underset(III) textChloro benzene (A) I>II>III (B) II>I>III (C) II>III>I (D) I>III>II

Tardigrade Admin · Accepted Answer

The tendency towards nucleophilic substitution is governed by the ease of leaving of the halide present in the substrate and the stability of carbocation formed.
Benzoyl chloride has a reactive carbon for an attack by a nucleophile. Benzyl chloride is a more reactive than aromatic halide due to the presence of double bond character on chlorobenzene.
Hence the order of reactivity is:

I > II > III
