Chapter 12, Problem 102E

Interpretation Introduction

Interpretation:

The boiling point trend of the given compounds is to be explained on the basis of the dispersion forces.

Concept introduction:

The dispersion forces magnitude depends upon the size of the electron cloud. Generally, on moving down the group the size of the electron could increases, as a result the boiling point increases on moving down the group if other factors are same.

The polar molecule containing a hydrogen atom $\left(\text{H}\right)$ that is directly bonded to high electronegative atoms fluorine, nitrogen $\left(\text{N}\right)$, or oxygen $\left(\text{O}\right)$ exhibits additional interaction called hydrogen bonding.
