Chapter 2, Problem 2.53P

Interpretation Introduction

Interpretation:

Compounds A-D are to be ranked in order from the lowest to the highest boiling points.

Concept introduction:

Compounds with strong intermolecular forces have higher boiling points. The strength of the intermolecular interactions increases from low to high as follows: $\text{Induced dipole - induced dipole < Dipole–dipole < Hydrogen bonding <Ion–dipole < Ion–ion}$ The induced dipole-induced dipole interactions become stronger with a greater

polarizability. Dipole-dipole interactions become stronger with larger dipole moments. Hydrogen bonding becomes more extensive with a greater number of potential H-bond donors and H-bond acceptors.
