What is polar and non polar solvent
  • 1 answers

Gaurav Seth 6 years, 8 months ago

 A molecule is said to be polar if it posses nonzero dipole moment (electronegativity difference and without symmetry).

Polar molecules Non-polar molecules
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 molecules is mainly due to electronegativity difference between bonding atoms. 2.In non-polar molecules the dipole moment is zero due nearly equal in electronegativity of bonding atoms and also due to symmetry in structure.
3.Generally polar molecules 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
