Question

Answer option C)

Order of inermolecular strength

Ionic interaction > H-bond interaction > dipole-dipole interaction > induced dipole interaction > London dispersion

London dispersion or van der walls interaction directly proportional to the surface (size) of the molecule.

CH3COOH has H-bonding interaction

Cl2 has induced dipole interaction

CH4 and Ar will have only London dispersion

Ar is bigger in size and CH4 will have lesser surface area than Ar.

So order

CH4 < Ar < Cl2 < CH3COOH

Explanation / Answer

(C) CH3COOH in water (D)HNO3 in water 12. List the substances Ar, Cl2, CHs, and CH3COOH in order of increasing strength of intermolecular attractions. (A) CH4
