For each of the given pair of compounds, member having the higher boiling point should be identified. Concept introduction: Intermolecular forces are much weaker than the chemical bonds but they are largely responsible for the structure of any solid or condensed phase. Dispersive forces are intermolecular attractive forces arisen from an instantaneous dipole-induced dipole attraction between molecules. In the molecules containing hydrogen attached to a highly electronegative atom, the intermolecular electrostatic attraction forces are very strong between the hydrogen of one molecule and the electronegative atom of another, this is called hydrogen bonding. Vapor pressure decreases and boiling point increases with increase in strength of intermolecular forces.
