Question

benzene reacts with acetyl chloride in presence of anhydrous AlCL3 to give

Answer 1

AlCl3 is considered to be a Lewis Acid or in simpler words an “electron hungry species”. So, when it sees Acetyl Chloride (CH3COCl) it extracts the -Cl minus from the latter and itself gets transformed into AlCl4 minus. Now it is quite stable because his hunger has been satisfied.

Now it leaves behind an electrophile -COCH3 minus. We all know that benzene undergoes aromatic electrophilic substitution reactions. As a result the other electrophile gets attached to the benzene ring thereby forming Acetophenone (C6H5COCH3).

AlCl3 is also a catalyst in this reaction because it gives off its Cl minus after the end of reaction and HCl is formed as bye product.

The mechanism wasn't quite required but you know it's always better to learn it

Answer 2

Answer:

Acetophenone.

Explanation:

• In the presence of anhydrous aluminium chloride, benzene interacts with acetyl chloride to create acetophenone. The reaction is a Friedel-Craft reaction in which the aromatic ring receives an acyl group. Friedel-Craft acylation entails the addition of acid chloride with the aid of a Lewis acid catalyst such as aluminium chloride AlCL3
• The major result of the Friedel-Craft acylation process is a ketone. An electrophilic substitution is used to convert benzene to acetophenone, in which an acyl group is linked to the benzene ring. The Lewis acid catalyst combines with the acyl chloride to generate a complex in which the acyl chloride loses its chloride ion and forms the acylium ion RCO, which functions as an electrophile and is stabilised by resonance.
• benziene  reacts with acetyl chloride in presence of unhydrate ALCL3 and gives acetophenon.
• After that, the acylium ion attacks the benzene ring, generating an intermediate complex that deprotonates and protonates the chloride to generate hydrochloric acid.
