Non polar organic molecules are ___________ in water?
Correct answer: B. Insoluble
- A. Soluble
- B. Insoluble
- C. Partially soluble
- D. Depends upon condition
Explanation
Nonpolar molecules do not form favourable interactions with polar water molecules, so they are generally insoluble and tend to aggregate away from water. This hydrophobic behaviour is important in the formation of lipid bilayers. Students may choose partially soluble because very small amounts can sometimes disperse, but the standard biological classification is insoluble in water.

About Biological Importance of Water
Water supports life through its polarity, hydrogen bonding and ability to dissolve ionic and polar substances. Its high specific heat, heat of vaporization, cohesion, adhesion and incompressibility help regulate temperature, transport materials and maintain structure, while hydrolysis and osmosis depend directly on water.
