Vedclass · Answer

(A) The reaction involves the nucleophilic substitution of the chlorine atom in $3$-iodobenzyl chloride by the cyanide ion $(CN^-)$ from $NaCN$.This is an $S_N2$ reaction.The primary alkyl halide group $(-CH_2Cl)$ is much more reactive towards $S_N2$ substitution than the aryl iodide group.Therefore,the $Cl$ atom is replaced by the $CN$ group,while the iodine atom remains unaffected.The product is $3$-iodophenylacetonitrile.
