Explain elasticity using intermolecular force.

Assertion: With increase of temperature, elastic property of a substance decreases. Reason: Elasticity is due to intermolecular forces which decreases with the increase of intermolecular distance.

Differentiate between rubbers and plastics on the basis of intermolecular forces.

The relative strength of intermolecular forces in bond decreasing order is –

Which of the following polymers can have strong intermolecular forces ?

The polymer containing strong intermolecular forces, e.g., hydrogen bonding is:

Arrange the following polymers in an increasing order of intermolecular forces , fibre, plastic , elastomer .

Arrange the following polymers in an increasing order of intermolecular forces , fibre, plastic , elastomer .

In which of the following mixtures, the London dispersion force acts as major intermolecular force of attraction ?

Assertion Ionic compounds tend to be non-volatile Reasoning Intermolecular forces in these compounds are weak .

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 (CH_(3)CH_(2)CH_(2)CH_(2)CH_(2)CH_(3)) , glycernine (CH_(2)OHCH(OH)CH_(2)OH)
