The Correct Option is C
Solution and Explanation
- (I) Benzenesulphonyl Chloride: This compound reacts with amines to form sulphonamide derivatives. It is used in the Hinsberg test, so it corresponds to (b) Hinsberg reagent.
- (II) Sulphanilic acid: This compound has an amino group and a sulfonic acid group, and it can exist as a zwitterion under certain conditions. Therefore, it corresponds to (a) Zwitterion.
- (III) Alkyl Diazonium salts: These salts are used in the azo dye synthesis and can react to form colored dyes. Thus, it corresponds to (c) Dyes. - (IV) Ary1 Diazonium salts: Ary1 diazonium salts can undergo reduction reactions to form alcohols, making them relevant to (d) Conversion to alcohols.
Thus, the correct matching is 1-a, II-b, III-c, IV-d. The correct answer is Option (3).

(c) Increasing order of solubility in water: C$_6$H$_5$NH$_2$, (C$_2$H$_5$)$_2$NH, C$_6$H$_5$NHCH$_2$CH$_3$ - Give plausible explanation for each of the following:
Amides are less basic than 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.
