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


(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
