Question

Nitration of benzene is carried out with conc. $\mathrm { H } _ { 2 } \mathrm { SO } _ { 4 }$is to provide

• A. Nucleophile during the reaction
• B. Free radical during the reaction
• C. Electrophile during the reaction
• D. Catalyst during the reaction.

Answer 1

Answer: (C)

Electrophile during the reaction

Answer 2

: Electrophile $\mathrm { NO } _ { 2 } ^ { + }$ is generated by the help of $\mathrm { H } _ { 2 } \mathrm { SO } _ { 4 }$In absence of $\mathrm { H } _ { 2 } \mathrm { SO } _ { 4 }$a nucleophile $\mathrm { NO } _ { 3 } ^ { - }$ will be formed which will not helpful in electrophilic substitution.
