Explanation:
- the polar substances dissolve in solvent polar in nature such as water where is non polar substances dissolve in substances which are non polar in nature. Such as benzene and Calcium tetrachloride
- covalent bond is formed by the sharing of the electrons where is the electrovalent bond is formed by the exchange of the electrons between the electropositive and electronegative ions
