The more strongly an atom attracts the electrons in its bonds, the larger its electronegativity. Electrons in a polar covalent bond are shifted toward the more electronegative atom; thus, the more electronegative atom is the one with the partial negative charge. The greater the difference in ...
Polar Molecules Note: Not all molecules with polar bonds are polar molecules
Both molecules have polar covalent bonds. According to the data in Figure 8.20, the electronegativity difference between a hydrogen atom and a oxygen atom is 1.24. The electronegativity difference between a chlorine atom and a carbon atom is 0.61. Although these electronegativity differences vary, a...

Ionic Character and Electronegativity To determine when bonds are ionic, polar covalent, or non-polar covalent (these options are known as ionic character), it is essential to have a grasp on the concept of electronegativity, first. Electronegativity is a numerical value given to each element, ...
When the electrons in the bond are not shared equally between the two atoms, a polar bond is formed. One end of the bond will have a partial positive charge as it is electron-deficient, and the other end will have a partial negative charge as it is electron-rich....

is composed of a bond polarity term, which measures the contribution due to the change in the electronegativity difference between the atoms in the bond, which is broken, and a polar relaxation term, which accounts for the substituent-dependent group electronegativity changes in the remaining bonds...
