Question

give the types of intermolecular force..... ​

Answer 1

Answer:

Intermolecular forces are electrostatic in nature and include van der Waals forces and hydrogen bonds. .The three major types of intermolecular interactions are dipole–dipole interactions, London dispersion forces (these two are often referred to collectively as van der Waals forces), and hydrogen bonds.

Answer 2

.$\bf\large\underline\green{Answer:-}$

There are two types of intermolecular forces -

i) Cohesive force

ii) Adhesive force.

i) Cohesive force:

The force of attraction between the molecules of the same substance is called cohesive force or force of cohesion. The force of attractionbetween two air molecules or that between two water molecules is a cohesive force. Cohesive force is strongest in solids and weakest in gases. This is the reason why solids have a definite shape and gases do not. Small droplets of liquid coalesce into one and form a drop due to this force.

ii) Adhesive force:

The force of attraction between the molecules of different substances is called adhesive force or force of adhesion. The force of attraction

between glass and water molecule is a force of adhesion.
