Answer 1

Dear User,
Diazotisation of aniline followed by reaction with Cuprous Bromide will yield mono Bromobenzene. The overall reaction is called Sandmeyer's Reaction. The conversion is shown below :

Answer 2

Explanation :

Step 1 : First, primary aromatic amine (Aniline) react with the nitrous acid at low temperature, result in the formation of diazonium salt (benzenediazonium chloride). This reaction is known as diazotisation reaction.

Step 2 : Second, benzenediazonium chloride salt react with the copper bromide which result in the formtaion of bromobenzene. This reaction is known as sandmeyer reaction.
