Question

Provide the structures of the major resonance contributors when nitrobenzene reacts with an electrophile in electrophilic aromatic substitution at the meta position. Use -Cl as an electrophile.

Answer 1

See explanation

Step-by-step explanation:

Benzene is less reactive to substitution reaction compared to the benzene containing a substituent group. A substituted benzene retains the aromatic ring while having a particular substituent which may facilitate or slow down the substitution reaction at specific positions on the benzene ring.

When chlorine is used as the electrophile, the structures that result from the substitution of C6H5NO2 at the stated position are shown in the image attached to this answer.
