Answer 1

The product is benzamide derivatives the reaction of C with A to form product is known as Aniline

Explanation:

1.When an amide is treated with bromine in an aqueous or ethanolic solution of sodium hydroxide, degradation of amide takes place leading to the formation of primary amine. This reaction involving degradation of amide and is popularly known as Hoffmann bromamide degradation reaction.

C6H5CONH2+4KOH+Br2→C6H5NH2+K2CO3+2KBr+2H2O

2.This reaction is used for the conversion of a primary amide to a primary amine with one less carbon atom.

3.The reaction of an amidine with a hypervalent iodine reagent affords an initial carbodiimide, which then reacts with an amine to generate the observed guanidine product . An analogous version of the Hofmann rearrangement has been reported with sulfonamide
