–NO2 group is an electron withdrawing group, hence it deactivates the benzene ring by decreasing the electron density on it.
Therefore, nitrobenzene does not undergo Friedel-Craft acylations.
Hence, both Assertion and Reason are false.

Directions: In the following question, two statements are given. One i...
Explanation:
Assertion:
- The assertion states that p-O2N – C6H5COCH3 is prepared by Friedel-Crafts acylation of nitrobenzene.
Reason:
- The reason given is that nitrobenzene easily undergoes electrophilic substitution reaction.
Explanation:
- The given assertion and reason are both incorrect. p-O2N – C6H5COCH3 is actually prepared by the acylation of nitrobenzene with acetyl chloride or acetic anhydride in the presence of a Lewis acid catalyst like AlCl3. This reaction is a Friedel-Crafts acylation process.
- Nitrobenzene does not easily undergo electrophilic substitution reactions due to the presence of the strongly deactivating nitro group (-NO2) which reduces the electron density on the benzene ring. This makes it less reactive compared to benzene in electrophilic aromatic substitution reactions.
Therefore, the correct answer is option 'D' - Both Assertion and Reason are false.
