Which of the following statements is incorrect?a)Cationic detergents h...
Explanation:
The incorrect statement is option B: Bacteria can degrade detergents containing highly branched chains.
Reasoning:
Cationic detergents have germicidal properties:
Cationic detergents, also known as quaternary ammonium compounds, have positively charged hydrophilic heads and hydrophobic tails. These detergents are effective in killing bacteria, viruses, and other microorganisms. They disrupt the cell membranes of the microbes, leading to their death. Therefore, the statement that cationic detergents have germicidal properties is correct.
Bacteria can degrade detergents containing highly branched chains:
Detergents containing highly branched chains, such as alkylbenzenesulfonates, are not easily biodegradable. Bacteria typically have limited ability to degrade these highly branched chains due to their complex structures. Therefore, the statement that bacteria can degrade detergents containing highly branched chains is incorrect.
Some synthetic detergents can give foam even in ice cold water:
Synthetic detergents have the ability to produce foam even in ice-cold water. This is due to their unique chemical structures, which allow them to lower the surface tension of water and form stable foam. Unlike soaps, which are made from natural fats and oils and are not effective in hard water, synthetic detergents can produce foam in various water temperatures and water hardness conditions. Therefore, the statement that some synthetic detergents can give foam even in ice-cold water is correct.
Synthetic detergents are not soaps:
Synthetic detergents and soaps are two different types of cleaning agents. Soaps are made from natural fats and oils, while synthetic detergents are derived from petroleum or other non-renewable resources. Soaps have a polar and non-polar end, which allows them to interact with both water and oil, enabling them to remove dirt and grime. Synthetic detergents, on the other hand, have a synthetic surfactant as their active ingredient. They are specifically designed to remove dirt and stains from various surfaces. Therefore, the statement that synthetic detergents are not soaps is correct.
Therefore, the incorrect statement is option B: Bacteria can degrade detergents containing highly branched chains.

Usme lika hai bacteria never degrade non biodegradable material or branched chain detergent. So they are harmful and create pollution. So b option wrong. Other statement is exact line of ncert. And all are factual
