Which of the following is an anionic detergent ? CH3(CH2)16CH2OSO3Na

Question : Which of the following is an anionic detergent ?

(1) CH₃(CH₂)₁₆CH₂OSO₃Na

(2) CH₃(CH₂)₁₆N(CH₃)₃Cl^–

(3) CH₃(CH₂)₁₆COO(CH₂CH₂O)_nCH₂CH₂OH

(4) C₅H₅SO₃Na

Answer : From all above options the correct answer is “(1) CH₃(CH₂)₁₆CH₂OSO₃Na” it means CH₃(CH₂)₁₆CH₂OSO₃Na is an anionic detergent .

explanation of answer : reason behind this answer is that As it is sodium salt of sulphonated long chain alcohol. So, group makes it anionic that is why we have given this option as for our correct answer as per question requirement. In short we can say that CH₃(CH₂)₁₆CH₂OSO₃Na is an anionic detergent.
