Vedclass · Answer

(B) Friedel-Crafts alkylation has several limitations:$1$. Aniline forms a complex with the Lewis acid $(AlCl_3)$,which deactivates the ring,making it impossible to undergo Friedel-Crafts alkylation.$2$. Polyalkylation is a major drawback because the alkyl group introduced is electron-donating,which activates the ring towards further substitution.$3$. Carbocation rearrangement occurs when using primary alkyl halides in the presence of a strong Lewis acid like $AlCl_3$.$4$. Nitrobenzene is a strongly deactivating group and is often used as a solvent in Friedel-Crafts reactions because it does not react with the Lewis acid catalyst.Therefore,the statement that 'Polyalkylation is not possible' is incorrect.
