Table sugar (sucrose) is a classic example; its numerous hydroxyl groups form hydrogen bonds with water, making it highly soluble. The positive ends of water molecules are attracted to negative regions of the solute, and the negative ends of water are attracted to positive regions.
How Chemical Interactions Drive Polar Compounds to Dissolve in Water
For a substance to dissolve readily in water, it must be able to interact favorably with these polar molecules. These solute-solvent interactions, often involving hydrogen bonding if the solute has H-bond donors or acceptors, release energy.
If the energy released is greater than the energy required to break the original solute-solute and solvent-solvent bonds, the compound will dissolve. This creates a strong dipole moment, with a partial negative charge on the oxygen and partial positive charges on the hydrogens.
How Chemical Interactions Drive Polar Compounds to Dissolve in Water
Even polar compounds can have limited solubility if their nonpolar portion is too large. Polar compounds, which also have uneven charge distributions, can form strong interactions with water, making them generally soluble.
