Which one of the following is not a property of water?
Correct answer: A. Hydrophobic properties
- A. Hydrophobic properties
- B. Hydrophilic properties
- C. Very good solvent
- D. Strong surface tension
Explanation
Hydrophobic properties refer to the tendency of certain substances to repel or not mix well with water. Hydrophobic substances are typically non-polar and do not readily dissolve in water. Instead, they tend to clump together or form separate phases. This property is often observed in substances like oils, fats, and waxes but not in water. Therefore, the correct statement for a property that is not associated with water is "A".

About Biological Molecules
The chapter covers water's polarity and biological roles, carbohydrates, lipids, proteins and nucleic acids, including their monomers, bonds, structures and functions. It also distinguishes RNA from DNA and explains conjugated molecules such as glycoproteins, glycolipids and nucleoproteins, which combine organic molecules with a non-protein component.
