Question

What are dipole-dipole forces?

Answer 1

Dipole-dipole forces

• Dipole-dipole forces exist between molecules that have a permanent dipole.
• Only partial charges are involved in this type of force. So this interaction is stronger than London forces but weaker than ion-ion interaction.
• The attractive force reduces as the distance between the dipoles increases.

The dipole-dipole interaction between two $\mathrm{HCl}$ molecules is as follows:-
