• Note that a polar bond results when the bonding pair is drawn more toward one atom than the other• Electronegativity is a measure of the ability of an atom in a molecule to draw bonding electrons to itself.9.5 Polar Covalent Bond and Electronegativity• This “attraction or pulling” of electrons causes a separation of charge within the bond.– Dipole moment is formed.• The greater the difference, the more polar the bond.
