Question

Which of the following are anionic detergents?

• A. Sodium salts of sulphonated long chain hydrocarbons.
• B. Quaternary ammonium salt of amine with acetate ion.
• C. Sodium salts of sulphonated long chain alcohol.
• D. Ester of stearic acid and polyethylene glycol.

Answer 1

Answer: (A), (C)

Sodium salts of sulphonated long chain alcohol.

Analysing the options

Option (A):

The sodium salts of sulfonated long chain alcohols are anionic detergents.



Option (B):

Esters of stearic acid and polyethylene glycol are known as non-ionic detergents.



Option (C):

Quaternary ammonium salts of amines with acetates, chlorides or bromides as anions are cationic detergents.

Example: Cetyltrimethylammonium bromide



Option (D):

The sodium salts of sulphonated long chain hydrocarbons are anionic detergents.



So, options (A) and (D) are the correct answers
