Q. 67

Match the compounds given in Column I with the items given in Column II.

Class 12th Chemistry - Exemplar 13. Amines

Answer :

(i) Benzene sulphonyl chloride - (b) Hinsberg reagent

(ii) Sulphanilic acid - (a) Zwitter ion

(iii) Alkyl diazonium salts - (d) Conversion to alcohols

(iv) Aryl diazonium salts - (c) Dyes

(i) Benzene sulphonyl chloride - (b) Hinsberg reagent

Benzenesulphonyl chloride or, C₆H₅SOCl is commonly known as Hinsberg’s reagent. Hinsberg’s reagent can be used to distinguish primary, secondary and tertiary amines.

(ii) Sulphanilic acid - (a) Zwitter ion

The net charge on sulphanilic acid is zero. Therefore, Sulphanilic acid is a zwitter ion or dipolar ion.

(iii) Alkyl diazonium salts - (d) Conversion to alcohols

When alkyl diazonium salts are treated with water molecules, they are converted to alcohols.

(iv) Aryl diazonium salts - (c) Dyes

A colourless substance ‘A’ (C6H7N) is sparingly soluble in water and gives a water soluble compound ‘B’ on treating with mineral acid. On reacting with CHCl3 and alcoholic potash ‘A’ produces an obnoxious smell due to the formation of compound ‘C’. Reaction of ‘A’ with benzenesulphonyl chloride gives compound ‘D’ which is soluble in alkali. With NaNO2 and HCl, ‘A’ forms compound ‘E’ which reacts with phenol in alkaline medium to give an orange dye ‘F’. Identify compounds ‘A’ to ‘F’.
