Which statement is not true for a detergent molecule?
It is sodium salt of fatty acid
- Detergents are surface-active agents that have a non-polar (hydrophobic) organic part and a polar (hydrophilic) functional group, typically the ionic head, which makes them soluble in water.
- Detergents are generally synthetic molecules and are not always sodium salts of fatty acids, which is a characteristic of soaps. Soaps are the sodium salts of long-chain fatty acids, while detergents are synthesized from petrochemicals or other compounds.
- The correct description for detergent molecules is that they have a non-polar organic part and a polar organic part (not non-organic). Therefore, option (d) is the correct answer as it is not true for detergent molecules.
