JEE Main Chemistry question

Statement 1: Friedel-Craft's reaction between benzene and acetic anhydride in the presence of anhydrous AlCl₃ yields acetophenone and not polysubstituted products. Statement 2: Acetophenone formed poisons and catalyst preventing further reaction.

(A)Assertion is True, Reason is True; Reason is correct explanation for AssertionCorrect
(B)Assertion is True, Reason is True; Reason is not correct explanation for Assertion
(C)Assertion is True, Reason is False
(D)Assertion is False, Reason is True

Answer: (A)

Solution

Both statements are true, and the second correctly explains the first: the acyl (–COCH₃) group formed on the ring is strongly deactivating (electron-withdrawing by both induction and resonance), making the ring much less reactive toward further electrophilic substitution; additionally, the
