Question

Attractive forces operating between the molecules possessing permanent dipole is called:

• A. dipole-dipole force
• B. dipole-induced dipole forces
• C. dispersion forces
• D. hydrogen bonding

Answer 1

The correct option is A dipole-dipole force

Dipole-dipole force is the interaction between two permanent dipoles, i.e, an attraction between the positive end of one dipole and a negative end of another dipole or polar molecule.

For example- $HCl$ as shown in the figure.
