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.

metals are good conductor of electricity. it has free electrons on their surface. according to electron pool theory, each atom present in a metal crystal losses all of its valence electron and as a result a pool of free is form. these pool of electrons are free to move and   conduct electricity easily   while making metal as good conductor.

the correct answer is a. the ability of electrons to flow throughout the metal.
