A. Anionic detergent:${\text{CH}}_3-{({\text{CH}}_2)}_{10}-{\text{CH}}_2-\text{O}-\stackrel{\text{O}}{\stackrel{\left|\right|}{\underset{\text{O}}{\underset{\left|\right|}{\text{S}}}}}-{\text{O}}^{\ominus }{\text{Na}}^{\oplus }$

Sodium Lauryl sulphate is example of anionic detergent.

These are sodium salts of sulphonated long chain alcohols or hydrocarbons.
