46. Detergents are A.Sodium salts of fatty acids B.Sodium salts of sulphonic acids C.Sodium salt of benzoic acid D.None of the above
Answer: Option B Solution: detergent is a surfactant or a mixture of surfactants with cleansing properties in dilute solutions. These substances are usually alkylbenzene sulfonates, a family of compounds that are similar to soap but are more soluble in hard water, because the polar sulfonate (of detergents) is less likely than the polar carboxylate (of soap) to bind to calcium and other ions found in hard water.
