Correct Answer: B. Increases in molecular mass
Detail about MCQs
As carboxylic acids get larger (i.e., as their molecular mass increases), they tend to have more nonpolar hydrocarbon-like portions in their structure, which can interact favorably with the hydrophobic tails of water molecules. This increased interaction with water molecules leads to greater solubility in water.
