Question

Statement-1 : Friedel-crafts reaction between benzene and acetic anhydride in the presence of anhydrous $AlC{l}_3$ yields acetophenone and not poly substituted products.
Statement-2 : Acetophenone formed, poisons the catalyst preventing further reaction.

• A. Both Statement-1 and Statement-2 are true and Statement-2 is the correct explanation of Statement-1.
  
• B. Both Statement-1 and Statement-2 are true and Statement-2 is not the correct explanation of Statement-1.
  
• C. Statement-1 is true but Statement-2 is false.
  
  
• D. Statement-1 is false but Statement-2 is true.

Answer 1

The correct option is C

Statement-1 is true but Statement-2 is false.

Correct R: $C{H}_{3}CO$ group in acetophenone being electron-withdrawing reduces the electron density in the benzene ring, thereby preventing further electrophilic substitution.
