(C) Nitration of aromatic compounds is an electrophilic aromatic substitution reaction where the rate-determining step is the formation of the sigma c

Vedclass · Accepted Answer

The rate of nitration of benzene is greater than that of hexadeuterobenzene

Vedclass · Answer

(C) Nitration of aromatic compounds is an electrophilic aromatic substitution reaction where the rate-determining step is the formation of the sigma complex (arenium ion).Since the $C-H$ or $C-D$ bond cleavage occurs after the rate-determining step,there is no primary kinetic isotope effect observed.Therefore,the rate of nitration of benzene $(C_6H_6)$ and hexadeuterobenzene $(C_6D_6)$ is essentially the same.Statement $C$ is false because the rates are equal,not greater.

Among the following statements on the nitration of aromatic compounds,the false one is:
