Question

Identify the product in the following reaction 3,4,5-tribromoaniline ${\to }_{\text{(ii)}{H}_3{\left(\text{PO}\right)}_2}^{\text{(i)}diazotization}$ ?

• A. 3,4,5 - Tribromo nitroaniline
• B. 1,2,3 - Tribromobenzene
• C. 3,4,5 - Tribromophenol
• D. 2,4,6 - Tribromobenzene

Answer 1

Answer: (B)

3,4,5-tribromoaniline is undergoing diazotization reaction to produce diazonium salt. Diazonium salt easily decomposed by acid. Diazonium salt reacts hypo phosphorus acid to produce 1,2,3-tribromobenzene.
