The azo-dye (Y) formed in the following reactions is: Sulphanilic acid + NaNO$_2$ + CH$_3$COOH → X 
The Correct Option is D
Solution and Explanation
The reaction involves the diazotization of sulphanilic acid, which forms a diazonium salt. This diazonium salt then couples with the compound \( C_6H_5NH_2 \), leading to the formation of the azo-dye product \( Y \).
The structure of \( Y \) matches option (4) in which the diazonium ion is coupled with the benzene ring of \( C_6H_5NH_2 \), forming the characteristic azo linkage (\(-N=N-\)) between the two aromatic rings.
Thus, the correct answer is: Option (4)
Top Questions on Amines
Amines are usually formed from amides, imides, halides, nitro compounds, etc. They exhibit hydrogen bonding which influences their physical properties. In alkyl amines, a combination of electron releasing, steric and H-bonding factors influence the stability of the substituted ammonium cations in protic polar solvents and thus affect the basic nature of amines. Alkyl amines are found to be stronger bases than ammonia. Amines being basic in nature, react with acids to form salts. Aryldiazonium salts, undergo replacement of the diazonium group with a variety of nucleophiles to produce aryl halides, cyanides, phenols and arenes.
