Detailed explanation-1: -Answer and Explanation: A molecule with a partial positive charge on one side of the molecule and a partial negative charge on the other side of the molecule is called a polar molecule.

Detailed explanation-2: -Summary. Polar covalent compounds have molecules with a partial negative charge on one side and a partial positive charge on the other side. This occurs because the compounds contain polar bonds. In a polar bond, one atom attracts the shared electrons more strongly than the other atom does.

Detailed explanation-3: -polar bond: a covalent bond that has opposite partial charges on each side (one side partially positive and one side partially negative), because of unequal sharing of electrons. For example: The bond between H and Cl in the H-Cl molecule is a polar bond.

Detailed explanation-4: -Covalent molecules with this type of uneven charge distribution are polar. Molecules with polar covalent bonds have a positive and negative side.
