Vedclass · Answer

(D) In reaction $(d)$,a secondary alkyl halide reacts with a nucleophile in a polar aprotic solvent $(DMF)$.Polar aprotic solvents favor the $S_N2$ mechanism by not solvating the nucleophile strongly,keeping it reactive.Options $(a)$ and $(b)$ involve tertiary halides,which favor the $S_N1$ mechanism.Option $(c)$ involves alcoholic $KOH$ and heat,which favors the elimination $(E2)$ mechanism.

Which of the following reactions is expected to take place by the $S_N2$ mechanism?
