Q. Dipole-induced dipole interactions are present in which of the following pairs?
A) H₂O and alcohol
B) Cl₂ and CCl₄
C) HCl and He atoms
D) SiF₄ and He atoms
Explanation
[Solution from source] HCl has a permanent dipole, which induces a temporary dipole in the non-polar He atom: a dipole–induced dipole interaction. Water and alcohol have dipole–dipole (H-bond) forces, while Cl₂/CCl₄ and SiF₄/He are both non-polar, giving only dispersion forces. Answer (3).
