Solution

The correct option is C $$(A) \rightarrow (ii) \, (B) \rightarrow (i) \, (C) \rightarrow (iv) \, (D) \rightarrow (iii) $$
(i) Benzene-sulphonyl chloride is the Hinsberg reagent

This is used to distinguish between $$1^o,2^o$$ and $$3^o$$ amine.
(ii) Sulphanilic acid rearranging to zwitterion

(ii) Alkyl diazonium salts lose nitrogen gas and then treated with water to convert to alcohol.
(iv) Aryl diazonium salts are coupled with aromatic amines/phenol to form dyes.
A) Benzenesulphorylchloride $$\longrightarrow$$ Hinsberg Reagent
B) Sulphanilic Acid $$\longrightarrow$$ zwitterion
C) Alkyldiazonium salts $$\longrightarrow$$ Conversion to alcohols
D) Aryldiazonium Salts $$\longrightarrow$$ Dyes
