Polar covalent bonding type of chemical bond where a pair of electrons are unequally shared between two atoms


There are two types of covalent bonding:
1. Non-polar bonding with an equal sharing of electrons.
2. Polar bonding with an unequal sharing of electrons. The number of shared electrons depends on the number of electrons needed to complete the octet.

Polarity occurs because one of the atoms in a covalent bond has a greater electronegativity than the other, which makes it attract the shared electrons more strongly. The uneven sharing of the electrons creates a dipole shift, which means that the side with the more electronegative atom has a slightly negative charge and the end with the less electronegative atom has a slightly positive charge.
