Concept Introduction:
A polar bond is a type of
Polarity: Polarity is a separation of electric charge that leads to a molecule or its chemical groups to have an electric dipole moment.
The polarity is determined by the electronegativity difference of atoms bonded to each other. The larger difference in electronegativity accounts for the more polar bond.
Dipole moment: Dipole moment is a measure of the unequal sharing of electrons in a molecule. In this one atom have a negative charge and one atom have a positive charge.
The arrow points from less electronegative element to more electronegative element and that show the direction of the dipole.
Electronegativity: Polar molecules must contain polar bonds due to a difference in electronegativity between the bonded atoms. The capability of an atom to attract the shared electrons in a chemical bond is defined as electronegativity.
