Viscosity of a liquid arises due to strong intermolecular forces existing between the molecules. Stronger the intermolecular forces, greater is the viscosity. Name the intermolecular forces existing in the following liquids and arrange them in the increasing order of their viscosities. Also give reason for the assigned order in one line. Water, hexane , glycerine

(a) Hexane has Vander Waal force of attraction present as the intermolecular force.
(b) Water has hydrogen bonding present in the form of intermolecular forces
(c) Glycerin has hydrogen bonding present as the intermolecular force
Hexane < water < glycerine
The reason behind this order is that in hexane, weak bonding forces exist; therefore, it has the least viscosity, whereas, in water and glycerine dipole-dipole interaction and extensive H-bonding are present. Glycerine has the strongest intermolecular forces. Therefore, the order of viscosity is-
