The hydrogen-chlorine H-Cl bond is polar. You can determine this by looking at the electronegativity values of the two atoms involved in the bond. Electronegativity is a measure of an atom's ability to attract electrons in a covalent bond.Hydrogen has an electronegativity value of 2.1, while chlorine has an electronegativity value of 3.0. The difference in electronegativity values between the two atoms is 0.9 3.0 - 2.1 . Generally, if the electronegativity difference between two atoms is greater than 0.5, the bond is considered polar.In a polar bond, the more electronegative atom in this case, chlorine will have a partial negative charge, while the less electronegative atom hydrogen will have a partial positive charge. This creates a dipole moment, which is a measure of the bond's polarity.
