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

H₂O and alcohol

Cl₂ and CCl₄

HCl and He atoms

SiF₄ and He atoms

Answer

HCl and He atoms

Dipole-induced dipole interaction is present in the pair in which the first species is polar and the other is non-polar.
H₂O and alcohol both are non-polar so there exist dipole-dipole interactions in between them.
Cl₂ and CCl₄ both are non-polar so there exists induced dipole -induced dipole interactions in between them. Similarly is true for SiCl₄ and He atoms pair.

HCl is a polar molecule, whereas He atoms are non-polar, so in between them dipole-induced dipole interactions exist.
