Identify the major product formed in the following reaction sequence.
Correct answer
2
Step-by-step solution
The given reaction sequence involves two steps: Aniline reacts with a mixture of NaNO ₂ and HCl at low temperatures ( 0-5^ C ) to undergo diazotization. This forms benzene diazonium chloride. C ₆ H ₅ NH ₂ NaNO ₂, HCl C ₆ H ₅ N ₂^+ Cl ^- The benzene diazonium chloride is then treated with copper(I) bromide ( CuBr ). This is a Sandmeyer reaction, where the diazonium group is replaced by a bromide ion, releasing nitrogen gas. C ₆ H ₅ N ₂^+ Cl ^- CuBr C ₆ H ₅ Br + N ₂ The final major product is bromobenzene.
