Expert Answer
Molecules having two oppositely charged poles are called polar molecules.
The magnitude of electro negativity difference reflects the degree of polarity.
A polar solvent is one with a bond between molecules with substantially different charges.
Polar solutes are substances which dissolve in polar solvents, forming polar bonds or hydrogen bonds.
A solute will dissolve in a solvent if the solute-solvent forces of attraction are great enough to overcome the solute-solute and solvent-solvent forces of attraction. Dissolution often occurs when the solute-solvent interactions are similar to the solvent-solvent interactions, signified by the term like dissolves like. Hence, polar solutes dissolve in polar solvents.
