When benzene reacts with acetyl chloride (CH3COCl) in the presence of AlCl3, acetophenone is formed. The electrophile in this reaction will be:
Correct answer: A. CH3CO+
- A. CH3CO+
- B. AlCl3
- C. CH3+
- D. CH3COCl
Explanation
CH3COCl reacts with AlCl3 to form ----> AlCl4- and CH3CO+CH3CO+ has a positive charge thus it is an electrophile and attracted to nucleophiles i.e. negative charges.

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.
