An azo compoudn X is cleaved at the azo linkage by stannous chloride `SnCl_2` to form two amines 3-bromo-4-amino toluence and 2-methyl-4-aminophenol.
`A+BrarrX`
Which of the following is the soutable combination of A and B?

Options

A.
B.
C.
D.

Answer

C

Explanation

For the coupling reaction, diazonium ion should cantain some electron withdrawing groups and the other compound should have electron releasing groups, i.e., should behave like a good nucleophile. ltbr. Thus, formation of 3-bromo-4-amino toluene and 2-methyl-4-amino phenol also supports these structure for A and B.
