Question

Assertion : $p-O_2N-C_6 H_5 COCH_3$ is prepared by Friedel Crafts acylation of nitrobenzene.
Reason : Nitrobenzene easily undergoes electrophilic substitution reaction.

• A. If both assertion and reason are true and reason is the correct explanation of assertion
• B. If both assertion and reason are true but reason is not the correct explanation of assertion
• C. If assertion is true but reason is false
• D. If both assertion and reason are false

Answer 1

Answer: (D)

- $NO _{2}$ group is electron withdrawing group, hence deactivate the benzene ring by decreasing the electron density on it.
$\therefore $ nitrobenzene does not undergo Friedel-Craft acylations.
