"A. A polar bond is a bond in which there is a molecule that has a slightly positively charged end, and a slightly negatively charged end; there is unequal sharing." Whenever a shared pair of electrons are not equally shared, a polar covalent bond is created. This type of bonding comes about when one of the elements' electronegativity is higher than the other. HCL, for example, chlorine is negatively charged while hydrogen is positively charged. On the other hand, a nonpolar covalent bond is one where electrons involved in bonding are evenly distributed between two or more atoms. The redistribution of electrical charge between the two atoms is balanced in a nonpolar covalent bond.

A) polar bond is a form of a covalent bond in which there is a molecule that is slightly positively charged and one that is somewhat negatively charged end. The two molecules are not evenly distributed between the bonded atoms. Molecules with dipoles are called polar molecules.

Answer B: polar bond is a kind of covalent bond in which the electrons are not evenly distributed between the bonded atoms. This uneven distribution of electrons will create a dipole between the ions. Molecules that have dipoles are called polar molecules.
