polar compound

po·lar com·pound

a compound in which the electric charge is not symmetrically distributed, so that there is a separation of charge or partial charge and formation of definite positive and negative poles, for example, H2O. See also inorganic compound.

polar compound

A molecule with distinct electrical charges in different regions, i.e., a positive charge in one region and a negative charge in another.
