Reaction of hexamethylbenzene with methyl chloride and aluminum chloride gave a salt a, which, on being treated with aqueous sodium bicarbonate solution, yielded compound b. suggest a mechanism for the conversion of hexamethylbenzene to b by correctly inferring the structure of a

-

The first step involves reaction of methyl chloride with AlCl₃.

Then the compound A generates by attack of pi bond on CH₃.

Then there is a rearrangement of the carbocation from 2° to 3°.

Finally a H⁺ is lost to give B

nacl is added to the aqueous of what? ? in order to get a proper answer you have to specify the exact composition of the aqueous solution.

i need mutiple choices
