Solution

Polar Molecules– A polar molecule is usually formed when the one end of molecule is said to possess more number of positive charges and whereas the opposite end of the molecule has negative charges, creating an electrical pole. When a molecule is said to have a polar bond, then the centre of the negative charge will be one side, whereas the centre of positive charge will be in different side. The entire molecule will be a polar molecule.

Non- Polar Molecules– A molecule which does not have the charges present at the end due to the reason that electrons are finely distributed and those which symmetrically cancel out each other are the non- polar molecules. In a solution, a polar molecule cannot be mixed with the non-polar molecule. For example, consider water and oil. In this solution, water is polar molecule whereas oil behaves as a non-polar molecule. These two molecules does not form a solution as they cannot be mixed up.
when oppositely charged ions approach each other , the attraction between the positive charge of cation and negative charge of anion and also the simultaneous repulsion between their nuclei and between their electrons results in the distortion , deformation or polarisation of the electron charge cloud of the anion.
