Acetophenone can be formed by which of the following reaction for benzene?
Correct answer: B. Acylation
- A. Alkylation
- B. Acylation
- C. Halogenation
- D. Nitration
Explanation
Benzene can be converted to acetophenone (methyl phenyl ketone) by Friedel-Crafts acylation. Firstly, we react ethanoyl chloride with aluminum trichloride (AlCl3) to obtain the electrophile 'CH3C+=O'. The electrophile, when provided with the correct conditions, in the presence of benzene, will undergo a substitution reaction to form acetophenone.

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.
