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

answer: any goods being imported from another country may be subject to issued by the federal government are tariffs

explanation:  

tariffs are a tax on anything that are imported from abroad. government use them to protect and boost their local industries and the thought is that they encourage consumers to buy local instead of importing and they will hope will protect jobs and economy in the country that implements them
