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

A

H2O\text{H}_2\text{O} and alcohol

B

Cl2\text{Cl}_2 and CCl4\text{CCl}_4

C

HCl\text{HCl} and He\text{He} atoms

D

SiF4\text{SiF}_4 and He\text{He} atoms

Step-by-Step Solution

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

  • H2O\text{H}_2\text{O} and alcohol: Both are polar molecules and primarily interact via dipole-dipole interactions and hydrogen bonding.
  • Cl2\text{Cl}_2 and CCl4\text{CCl}_4: Both are non-polar molecules, so they interact via London dispersion forces (induced dipole-induced dipole interactions).
  • HCl\text{HCl} and He\text{He} atoms: HCl\text{HCl} is a polar molecule with a permanent dipole, while Helium (He) is a non-polar noble gas atom. The permanent dipole of HCl\text{HCl} induces a temporary dipole in the He atom, leading to dipole-induced dipole interactions.
  • SiF4\text{SiF}_4 and He\text{He} atoms: Both are non-polar, so they interact solely through London dispersion forces. Therefore, the pair exhibiting dipole-induced dipole interactions is HCl\text{HCl} and He\text{He} atoms.
