Benzene reacts with acetyl chloride in the presence of catalyst AICI3 to give:
Correct answer: B. Acetophenone
- A. Aldehyde
- B. Acetophenone
- C. Benzyl Chloride
- D. Benzophenone
Explanation
The reaction of benzene with acetyl chloride(CH3COCl) in the presence of a catalyst like aluminum chloride (AlCl₃) is known as the Friedel-Crafts acylation reaction, which leads to the formation of Acetophenone (Aromatic ketone). Acetophenone is the correct product in this reaction. The other options, Aldehyde, Benzyl Chloride, and Benzophenone, are incorrect as they do not represent the product of this specific reaction.

About Benzene and Aromatic Compounds
Benzene has a planar ring of delocalised π electrons, giving aromatic stability and equal carbon-carbon bond lengths. The topic covers resonance, electrophilic substitution reactions such as nitration, halogenation, sulphonation and Friedel-Crafts reactions, along with substituent effects and the distinction between substitution in benzene and addition in ordinary alkenes.
