Verified step by step guidance

Understand that solubility in water is influenced by the ability of a molecule to form hydrogen bonds with water molecules. Functional groups that can form hydrogen bonds will increase solubility.

Examine the functional group —OH (hydroxyl group). This group can form hydrogen bonds with water due to the presence of the electronegative oxygen atom bonded to hydrogen, which makes it polar.

Consider the functional group —COOH (carboxyl group). This group contains both a carbonyl (C=O) and a hydroxyl (OH) group, both of which can form hydrogen bonds with water, enhancing solubility.

Analyze the functional group —COH (aldehyde group). The carbonyl group (C=O) within the aldehyde can form hydrogen bonds with water, contributing to increased solubility.

Conclude that all the listed functional groups (—OH, —COOH, —COH) can increase the solubility of organic compounds in water due to their ability to form hydrogen bonds.
