A polar covalent bond is a chemical bond in which two atoms share a pair of electrons unequally because one atom attracts the shared electrons more strongly. This unequal sharing creates partial positive and partial negative charges, turning the bond into a tiny electric dipole. Understanding what is a polar covalent bond helps explain the behavior of water, many biological molecules, acids, alcohols, and numerous other substances.
Introduction
Atoms commonly form bonds by sharing electrons,
