Question

Difference between polar and non-polar solvent.

Answer 1

Polar solvent	Non-polar solvent
1.Molecules in which dipole moment is not ‘zero’ are called polar solvents. Example: NaCl, HF, H2O…etc They does not posses any symmetry.	1.Molecules in which dipole moment is ‘zero’ are called non-polar solvents. Example: CCl4, H2, Cl2, O2…etc These compounds may posses symmetry.
2.The non-zero dipole moment in these solvent is mainly due to electronegativity difference between bonding atoms.	2.In non-polar solvent the dipole moment is zero due nearly equal in electronegativity of bonding atoms and also due to symmetry in structure.
3.Generally polar molecul dissolve in polar solvents. Ex: NaCl will dissolve in H₂O	3.Generally non polar molecules dissolve in non-polar solvents. Ex: CCl₄ will dissolve in Benzene
