Vedclass · Answer

(D) Compounds which cannot undergo Friedel-Crafts reaction are:$1$. Nitrobenzene: The $-NO_2$ group is a strongly deactivating group,which makes the ring electron-deficient and unsuitable for electrophilic substitution.$2$. Aniline: The $-NH_2$ group forms a complex with the Lewis acid catalyst $AlCl_3$ (e.g.,$C_6H_5NH_2 \cdot AlCl_3$),which deactivates the ring and prevents the reaction.$3$. $m$-nitroaniline: It contains both the strongly deactivating $-NO_2$ group and the $-NH_2$ group that forms a complex with the catalyst.$4$. $m$-dinitrobenzene: It contains two strongly deactivating $-NO_2$ groups,making the ring highly electron-deficient.Thus,a total of $4$ compounds cannot undergo Friedel-Crafts reaction.

Number of compounds from the following which cannot undergo Friedel-Crafts reactions is ............ toluene,nitrobenzene,xylene,cumene,aniline,chlorobenzene,$m$-nitroaniline,$m$-dinitrobenzene
