Vedclass · Answer

(D) The reactivity of benzylic halides toward $S_N2$ reactions is influenced by the electronic effects of substituents on the benzene ring. An electron-withdrawing group (like $-NO_2$) at the para position stabilizes the transition state of the $S_N2$ reaction by dispersing the negative charge that develops on the carbon atom during the nucleophilic attack. Conversely,electron-donating groups (like $-CH_3$) destabilize the transition state. Therefore,$p$-nitrobenzyl chloride is the most reactive toward $S_N2$ reaction among the given options.
