Question = Is glycerol polar or nonpolar ? Answer = glycerol ( C3H8O3 ) is Polar What is polar and non-polar? Polar "In chemistry, polarity is a separation of electric charge leading to a molecule or its chemical groups having an electric dipole or multipole moment. Polar molecules must contain polar bonds due to a difference in electronegativity between the bonded atoms.

Solvents having dielectric constant value of below 15 are generally considered as non-polar. The polar solvents can further classified into two sub-groups, protic and aprotic solvents. Protic solvents (water, methanol, ethanol etc.) solvate anions through hydrogen bonds whereas aprotic solvents (DMSO, DMF, acetone etc.) solvate cations through dipole moments.
