4.4 Polar Bonds

Polar Bonds are formed when one of the elements attracts the shared electrons more strongly than the second element. These bonds are somewhere between covalent and pure ionic bonds in character. There is asymmetry in the distribution of electron density. Usually in common expression we speak of electrons being shifted towards the more electronegative partner.

The unequal sharing of electrons leads to fractional electrical charges on atoms represented by the Greek letter delta
