Covalent compounds shows two types of bonding:

1. Polar bonding results with an unequal sharing of electrons. A polar bond is a type of covalent bond between two atoms or more in which electrons are shared unequally. Because of this, one end of the molecule has a slight, relative negative charge and the other a slight, relative positive charge. The compounds with this tyoe of bonding are called polar covalent compounds. For example: BF3; here boron has a slight positive charge and flourine has a slight negative charge.

2. Non polar bonding results when two identical non-metals equally share electrons between them. Non polar bonds are formed by bonding between non-metals consists of two electrons shared between two atoms. The compounds with non-polar bonding are called non-polar covalent compounds. For example: O2
