simple defintion of polar and non polar

Answer 1

Polar and nonpolar are terms used to describe the distribution of electric charge in a molecule.

Polar molecules have an unequal distribution of charge, resulting in a slight positive charge at one end and a slight negative charge at the other end. This charge separation is caused by differences in electronegativity between the atoms in the molecule.

Nonpolar molecules have an equal or nearly equal distribution of charge, resulting in no significant charge separation. This occurs when the atoms in the molecule have similar electronegativities or when the molecule is symmetrical.
