Assertion : Friedel-Crafts reaction betw...

Assertion : Friedel-Crafts reaction between benzene and acetic anhydride in the presence of anhydrous `AlCl_3` yields acetophenone and not poly substituted products.
Reason : Acetophenone formed poisons the catalyst preventing further reaction.

A

If both Assertion and Reason are correct and Reason is the correct explanation of Assertion.

B

If both Assertion and Reason are correct, but Reason is not the correct explanation of Assertion.

C

If Assertion is correct , but Reason is incorrect.

D

If both Assertion and Reason are incorrect .

Text Solution

Verified by Experts

The correct Answer is:
C
`CH_3CO` group in acetophenone being electron-withdrawing reduces the electron density in the benzene ring, thereby preventing further electrophilic substitution .
