(a)
To determine: The compound that has a higher boiling point in the given pair of compounds.
Interpretation: The compound that has a higher boiling point in the given pair of compounds is to be predicted.
Concept introduction: The important factors that affect the boiling points of organic compounds are hydrogen bonding, molecular weights, surface area and dipole moments. Boiling point of the compounds increases when hydrogen bonding is present between them. Boiling point increases, as the number of carbon atoms in the molecules increases.
