Question

The van der Waal's attractive forces operate between polar molecules having $>0$ and the non-polar molecules having $=0$ is:

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

Answer 1

Answer: (B)

dipole-induced dipole forces

Dipole-induced dipole forces attractive forces operate between polar molecules having $>0$ and the non-polar molecules having $=0$. Permanent dipole of the polar molecule induces dipole on the electrically neutral molecule by deforming or polarizing its electron cloud. The attractive forces between permanent dipole and induced dipole are called dipole-induced dipole forces.
So, the van der Waal attractive forces operate between polar molecules having $>0$ and the non-polar molecules having $=0$ is Dipole-induced dipole forces
Hence, option $B$ is correct
