Which type of intermolecular attractive force operates between all molecules?

Hydrogen bonding

Ionic bonding

Non- induced dipole forces

Ion dipole forces

Van-der wall forces

Explanation:

Intermolecular forces are the forces which operates at molecular level they may be attractive or repulsive in nature. But the given question ask only about attractive molecular forces. These are of basically  five types:-

1. Hydrogen bonding- It is the force of attraction between hydrogen atom and an electro-negative atom.

2 .Ionic bonding- It is the force of attraction between cationic and anionic pair.

3.Non - Induced dipole forces- It is the dipole- dipole interaction between permanent electromagnetic materials.

4.Ion-dipole forces- These bonds are stronger than hydrogen bond and also stronger than dipole-dipole bond.

Van-der walls forces- It is the force of attraction between uncharged molecules.
