$IV$

Vedclass · Answer

(B) The reaction sequence involves nucleophilic substitution followed by precipitation with silver ions. Compound $IV$ contains a benzylic iodide group $(-CH_{2}I)$. When treated with $NaOH$,the iodide ion $(I^{-})$ is displaced via an $S_{N}2$ mechanism to form an alcohol. The resulting $I^{-}$ ions react with $AgNO_{3}$ in the presence of $HNO_{3}$ to form a yellow precipitate of silver iodide $(AgI)$. Compounds $I$,$II$,and $III$ contain aryl halides where the halogen is directly attached to the benzene ring,making them resistant to nucleophilic substitution under these conditions.

Among the following compounds $I-IV$,which one forms a yellow precipitate on reacting sequentially with $(i)$ $NaOH$,$(ii)$ dil. $HNO_{3}$,and $(iii)$ $AgNO_{3}$?
