Explain the mechanism of Friedel craft's acylation reaction. |
Answer» Solution :Benzene REACTS with acetyl chloride in presence of anhydrous `AlCl_(3)` to form acetophenone. Mechanism Step 1 : GENERATION of electrophile `CH_(3)CO^(+)` `CH_(3) - CO - Cl + AlCl_(3) rarr CH_(3) - CO^(+) + AlCl_(4)^(Θ)` Step 2 : The electrophile `CH_(3)CO^(+)` attacks the benzene RING to form a carbocation which is reasonance stabilized.  Step 3: Loss of proton to GIVE acetophenone.
