(iii) Quarternary ammonium salt of amine with acetate ion.
(iv) Sodium salts of sulphonated long-chain hydrocarbons.
उत्तर
(i) Sodium salts of sulphonated long-chain alcohol.
(iv) Sodium salts of sulphonated long-chain hydrocarbons.
Explanation:
Sodium salts of sulphonated long-chain alcohol and sodium salts of sulphonated long-chain hydrocarbons are anionic detergents e.g., Sodium lauryl sulphate \[\ce{CH3(CH2)10CH2OSO3– Na+}\] and sodium dodecylbenzene sulphonate.
