Solubility of carboxylic acids:
Correct answer: B. Decreases with increase in molecular mass
- A. Decreases with increase of volume
- B. Decreases with increase in molecular mass
- C. Increases with increase in molecular mass
- D. None of these
Explanation
This option is generally correct. The solubility of carboxylic acids tends to decrease as the molecular mass of the carboxylic acid increases. This is because larger molecules have stronger intermolecular forces (such as van der Waals forces) that can make it more difficult for them to dissolve in a solvent. Smaller carboxylic acids with lower molecular masses are usually more soluble in water or other polar solvents.

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.
