Why is HCl called a polar molecule? Explain your reasoning. Polar Molecules: A molecule is considered polar if it has an overall dipole moment. The dipole moment of the compound depends if the compound has polar bonds and if the geometry of the compound will permit a net dipole moment. Bo...
A polar molecule is mostly positive on one side and mostly negative on the other. This difference allows the polar molecule...
