Which of the following statements is correct?
1. Cationic detergents have germicidal properties
2. Bacteria can degrade the detergents containing highly branched chains
3. Some synthetic detergents can give foam even in ice-cold water
4. Synthetic detergents are not soaps
(a, c, d)
(a) Cationic detergents are quarternary ammonium salts of amines with acetates, chlorides, or bromides as anions. These detergents have germicidal properties. Hence, option (a) is correct.
(b) Bacteria can not degrade the detergents containing highly branched chains, therefore in most of the detergents used these days, the branching is kept to a minimum so that the detergents become easily biodegradable. Hence, option (b) is incorrect.
(c) Some synthetic detergents can give foam even in ice-cold water. Hence, the option (c) is correct.
(d) Synthetic detergents are cleansing agents that have all the properties of soaps, but which actually do not contain any soap. Hence, option (d) is correct.
