Product C of the following reaction sequence will be

Step-by-step solution

Aniline on reaction with bromine water gives 2,4,6-tribromoaniline (A) as the major product due to the strong activating nature of the - NH ₂ group. Reaction of (A) with NaNO ₂/ HCl at 273-278 K (diazotization) yields 2,4,6-tribromobenzenediazonium chloride (B). Treatment of (B) with HBF ₄ forms 2,4,6-tribromobenzenediazonium fluoroborate. Heating this intermediate with NaNO ₂ and Cu replaces the diazonium group with a nitro group, forming 2,4,6-tribromonitrobenzene (C). To assign the IUPAC name, we number the ring
