... The Solubility of Covalent Compounds in Water Polar covalent compounds are very soluble in water. They often have OH groups that can form “hydrogen bonds” with water. Examples are table sugar (C12H22O11), ethanol (C2H5OH), ethylene glycol (C2H6O2) in antifreeze, and methanol (CH3OH). These also are ...
