(a)

Interpretation Introduction

Interpretation: The compound having the higher boiling point has to be identified.

Concept Introduction:

Boiling point: It is the temperature at which liquid converts to vapor. At boiling point the vapor pressure of liquid and the pressure of the surroundings are equal.

The boiling point of a liquid increases as the intermolecular forces within the compound increases.

Explanation

Boiling point is the temperature at which liquid converts to vapor. At boiling point the vapor pressure of liquid and the pressure of the surroundings are equal.

The intermolecular forces that operate in interhalogen are greater than those in halogen...
