its very simple just observe that all are very soluble in water except for greese.
the fact is the hydrogen bonds can beasily bond with hydrocarbons.. this is more like a chemistry question but i terms of surface tension the detergents weaken the tension by breaking the hydrogen bonds to form solutions but greeze can not do that
Some liquids such as oil and kerosene can destroy surface tension in water. Adding soap or detergent reduces surface tension in water. Increasing the temperature of the liquid reduces surface tension.
If there is any oil or oily compounds on the free surface of the water, then surface tension will be reduced. If you mix something to the water, then the surface tension will be changed. If you electrify the water then surface tension will be reduced.
thechnically all there is no answer bcs all of them recuces surface tension but just choose the least
The end of the detergent molecule which attaches to fat (grease) repels water molecules. ... This weakens the hydrogen bonds holding the water molecules together at the surface. The result is a break in the surface tension of the water.
A surfactant, at its most basic, is a substance that is designed to reduce the surface tension of a liquid.
The correct answer is **D. camphor**. Here's why:
A. **Soap solution**: Soap is a surfactant, which means it can reduce the surface tension of water.
B. **Detergent**: Like soap, detergent is also a surfactant and can lower the surface tension of water.
C. **Alcohol**: Alcohol can lower the surface tension of water.
E. **Grease**: Grease or any oil or oily compounds on the free surface of the water can reduce the surface tension.
However, **camphor** (option D) does not reduce the surface tension of water. Instead, it can move on the water surface due to the differences in surface tension caused by it. So, camphor does not cause a reduction in the surface tension of water. Hence, the correct answer is D. camphor..
