$(Trichloromethyl)benzene$ $(C_6H_5CCl_3)$

Vedclass · Answer

(C) Electrophilic aromatic substitution occurs at the meta position when the substituent on the benzene ring is a strongly electron-withdrawing group (deactivating group) that does not have lone pairs to donate via resonance.$1$. $Toluene$ $(-CH_3)$,$Ethylbenzene$ $(-CH_2CH_3)$,and $Chlorobenzene$ $(-Cl)$ are all ortho/para-directing groups. The alkyl groups are activating,and the chlorine atom,despite being deactivating,directs ortho/para due to resonance donation of its lone pair.$2$. In $(Trichloromethyl)benzene$ $(C_6H_5CCl_3)$,the $-CCl_3$ group is strongly electron-withdrawing due to the inductive effect of the three electronegative chlorine atoms. It lacks lone pairs for resonance donation,making it a meta-directing group.
