Compound A has a molecular formula C₇H₇NO on treatment wit...
Explanation:
Given information:
- Compound A has a molecular formula CHNO.
- On treatment with Br/KOH, A gives an amine B which responds to the carbylamine test.
- B on diazotisation and coupling with phenol gives an azo dye.
Analysis:
- The molecular formula of compound A is CHNO, which indicates the presence of a carbonyl group and a nitrogen atom.
- When compound A is treated with Br/KOH, it undergoes a Hofmann bromamide degradation reaction to form an amine B. This reaction involves the replacement of the carbonyl group with an amine group.
- The amine B responds to the carbylamine test, which is a characteristic test for primary amines.
- Further, when B undergoes diazotisation and coupling with phenol, it forms an azo dye. This reaction is specific to compounds containing a primary aromatic amine group.
Conclusion:
- Among the given options, only option B, CHCONH, fits the criteria based on the reactions described.
- Option B contains a carbonyl group (CONH) which can undergo the Hofmann bromamide degradation to form an amine. The resulting compound can respond to the carbylamine test and further undergo diazotisation to form an azo dye.
- Hence, the correct answer is option B, CHCONH.
