Vedclass · Answer

(C) Amines react with alkyl halides in excess to undergo exhaustive alkylation,resulting in the formation of a quaternary ammonium salt.Among the given options,$C_6H_5NH_2$ (aniline) is an amine,which reacts with excess methyl iodide $(CH_3I)$ to form a quaternary ammonium salt as shown below:$C_6H_5NH_2 + 3CH_3I \rightarrow C_6H_5N^+(CH_3)_3I^- + 2HI$Ethers ($C_2H_5OCH_3$ and $(CH_3)_2CHOC_2H_5$) do not form quaternary salts under these conditions,and nitro compounds $(C_6H_5NO_2)$ are not nucleophilic enough to undergo this reaction.

Which one of the following compounds forms a quaternary salt on reacting with excess methyl iodide?
