What is the mechanism of phthalic anhydride and m-xylene which results in 2-(2,4-dimethylbenzoyl) benzoic acid ? include the reaction with alcl3 to form a complex.

Explanation:

Pthalic anhydride on reacts with AlCl₃ forms a complex which on reaction with m-xylene gives 2-(2,4-dimethylbenzoyl) benzoic acid.

The mechanism the reaction follows is:

(a) Image 1.

The mechanism shows the formation of the complex of pthalic anhydride with aluminum chloride. AlCl₃ acts as Lewis base which gets attached to the nucleophilic oxygen of pthalic anhydride.

(b) Image 2.

The attack of the double of m-xylene to the oxygen bearing positive charge of pthalic acid which on protonation gives 2-(2,4-dimethylbenzoyl) benzoic acid.

"hydrogen bonding is the attraction of h atoms in the water molecule (slight + charge) to o atoms in a neighboring water molecule (slight - charge); it is a weak interatomic force. but it is still strong enough to the water molecules "stick" together."
