In the reaction This reactive species (most likely) is

A)  \[NO_{2}^{-}\]           

B)  \[NO_{2}^{+}\]

C)  \[N{{O}_{2}}\]          

D)  None of these

Correct Answer: B

Solution :

: Nitration of benzene involves the following sequence of reactions.     \[HN{{O}_{3}}+2{{H}_{2}}S{{O}_{4}}{{H}_{3}}{{O}^{+}}+2{{H}_{2}}SO_{4}^{-}+NO_{2}^{+}\] \[NO_{2}^{+}\]is an electrophile.
