A polar covalent bond is one in which the electrons are not shared equally between the two atoms.

Work Step by Step

In a polar covalent bond, the atom with the higher electronegativity holds on tighter to the electrons; therefore, the electrons spend more time with the atom that has the higher electronegativity and less time with the less electronegative atom. This would cause portions of the compound to take on partial negative and partial positive charges.
