Question

Dipole-induced dipole interactions are present in which of the following pairs?

Options

• HCl and He atoms

• SiF₄ and He atoms

• H₂O and alcohol

• Cl₂ and CCl₄

Answer 1

HCl and He atoms

Explanation:

Alcohol and H₂O are both polar compounds. Consequently, there exist dipole-dipole interactions (hydrogen bonding) between them.

While HCl is polar, SiF₄, He, Cl₂, and CCl₄ are nonpolar. As a result, there exist dipole-induced dipole interactions between the atoms of HCl and He.
