Hello candidate,

The given action between bromo benzene  undergoing reaction with acetyl chloride in the presence of aluminium chloride which is a weak acidic agent which helps in in removal of bromine as a leaving group and addition of acetyl group on the benzene ring. Here, the suitable solvent for carrying out this reaction should be a polar aprotic solvent because of the involvement of a lot of halogen groups of electronegativity which needs to be neutralized by the polar solvent.

Hope you found it helpful!!
