- NO 2 group is electron withdrawing group, hence deactivate the benzene ring by decreasing the electron density on it. ∴ nitrobenzene does not undergo Friedel-Craft acylations.

Q. Assertion : $p - O_{2} N - C_{6} H_{5} COC H_{3}$ is prepared by Friedel Crafts acylation of nitrobenzene.
Reason : Nitrobenzene easily undergoes electrophilic substitution reaction.

If both assertion and reason are true and reason is the correct explanation of assertion

If both assertion and reason are true but reason is not the correct explanation of assertion

If assertion is true but reason is false

If both assertion and reason are false

- $N O_{2}$ group is electron withdrawing group, hence deactivate the benzene ring by decreasing the electron density on it.
$∴$ nitrobenzene does not undergo Friedel-Craft acylations.
