Question

Intermolecular forces

* Relate properties of substances to the predicted Intermolecular bonding of the substances

Answer 1

Answer) Intermolecular forces are the forces that holds atoms and molecules of a substance together. It includes force of attraction and repulsion that works among atoms and different types of particles.

Intermolecular bonding affects the physical properties of a substance like melting point, boiling point, solubility etc.

Strong intermolecular bonding causes molecules to be hold more tightly which results in high melting point, boinling point , solubility.

Lower intermolecular bonding causes higher vapour pressure.

For liquids higher the intermolecular forces, higher is the viscosity.

Higher intermolecular forces , results in higher surface tension.
