Question

Quizplus · Accepted Answer

The reaction shown is a Friedel-Crafts acylation reaction, where benzene is being reacted with acetyl chloride (CH3COCl) in the presence of aluminum chloride (AlCl3) as a catalyst. The acetyl group (CH3CO) will attach to the benzene ring to form an aryl ketone.

The major product in this reaction will be ortho and para substituted products. This is because the intermediate carbocation is stabilized by resonance when the substituent is in the ortho or para position. Thus, the products formed will be majorly ortho and para substituted.

In option B, products II and III are the major ortho and para products respectively. So, B is the correct choice.
