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

Dipole-induced dipole interactions occur between a polar molecule (which has a permanent dipole moment) and a non-polar molecule or atom.

• $\text{H}_2\text{O}$ and alcohol: Both are polar molecules and primarily interact via dipole-dipole interactions and hydrogen bonding.
• $\text{Cl}_2$ and $\text{CCl}_4$: Both are non-polar molecules, so they interact via London dispersion forces (induced dipole-induced dipole interactions).
• $\text{HCl}$ and $\text{He}$ atoms: $\text{HCl}$ is a polar molecule with a permanent dipole, while Helium (He) is a non-polar noble gas atom. The permanent dipole of $\text{HCl}$ induces a temporary dipole in the He atom, leading to dipole-induced dipole interactions.
• $\text{SiF}_4$ and $\text{He}$ atoms: Both are non-polar, so they interact solely through London dispersion forces. Therefore, the pair exhibiting dipole-induced dipole interactions is $\text{HCl}$ and $\text{He}$ atoms.
