Which of the following is an anionic detergent?

Step-by-step solution

A. Anionic detergent: CH 3 − ( CH 2 ) 10 − CH 2 − O − S | | O | | O − O ⊖ Na ⊕ Sodium Lauryl sulphate is example of anionic detergent. These are sodium salts of sulphonated long chain alcohols or hydrocarbons. CH 3 − CH 2 10 − CH 2 − OH → H 2 SO 4 conc . CH 3 − CH 2 10 CH 2 − O − S | | O | | O − OH → NaOH aq CH 3 − ( CH 2 ) 10 − CH 2 − O − S | | O | | O − O ⊖ Na ⊕ Sodium lauryl sulphate (anionic detergent) B. Cationic deterge
