Question

What is the difference between polar and non polar molecules???

Answer 1

A polar molecule is a molecule that has oppositely charged regions, as a result of polar bonds within the molecule. They are asymmetrical, which means the polar bonds do not cancel out as the molecule is lopsided.

Non-polar molecules are molecules that have no oppositely charged regions and have no net dipole moment. This is due to either all of the covalent bonds within the molecule being non-polar, or that the polar bonds within the molecule cancel each other out, so is said to be symmetrical.

Therefore, all polar molecules contain at least one polar covalent, whereas not all non-polar molecules contain non-polar covalent bonds.
