Final answer:
Polar compounds have polar covalent bonds and dissolve in Water.
Step-by-step explanation:
Compounds with polar covalent bonds have electrons that are shared unequally between the bonded atoms. The polarity of such a bond is determined largely by the relative electronegativites of the bonded atoms. The asymmetrical charge distribution in a polar substance produces a dipole moment.
Water, being a polar molecule, readily dissolves ionic compounds and polar covalent compounds. These compounds are referred to as hydrophilic or "water-loving." On the other hand, nonpolar molecules, which do not readily dissolve in water, are called hydrophobic or "water-fearing."
Examples of polar compounds include amino acids and glucose, while examples of nonpolar compounds include hydrocarbons like decane (C10H22).
