Distinguish, differentiate, compare and explain what is the Difference between Polar and Non-Polar molecules. Comparison and Differences.

Difference between Polar and Non-Polar molecules

1. Covalent compounds are said to be polar when the shared electron moves towards the atom with the greater mass. Example: Cl2 molecule, CH4 molecule. Covalent compounds are said to be nonpolar when the shared Pair of electrons are at an equal distance from both the atoms involved in bonding. The atom towards which the electron pair shift gets a (slight negative charge) while the other atom acquires a (light Positive charge)

2. The polar covalent molecule has two centers of charge and this is known as “dipole”. In non-polar molecules, there is no charge separation and the molecule is electrically neutral.

3. In polar molecules, there is great difference in the electro negativity values of the atom. In the non-polar molecules, electro negativity difference between the atoms is zero.
