The amine shown is treated with $NaNO X_{2}$ and $HCl$ at 0-5 $^{\circ}$ C. Which structure is the product?

AStructure A
BStructure B
CStructure C
DStructure D

Answer: A

The compound shown is 4-chloroaniline, a primary aromatic amine. Diazotisation in the cold gives the arenediazonium chloride, here 4-chlorobenzenediazonium chloride. Above 5

^{\circ}

C it would start to hydrolyse to the phenol.
