(a)
Interpretation:
The substance in the given pair with lower boiling point is to be predicted.
Concept Introduction :
Boiling point is a temperature at which pressure exerted by surrounding on the liquid is equal to the vapor pressure of the liquid. In a liquid molecules or atom are close contact, the thermal energy are required to overcome the attraction between them. The attraction is nothing but intermolecular forces between them. The strength of inter molecular forces are,
