Question

Explain, in terms of intermolecular forces, why ammonia has a higher boiling point than the other compounds in the ta

Answer 1

Answer is: ammonia has a higher boiling point because it has stronger intermolecular forces.

Intermolecular forces are the forces between molecules. The stronger are intermolecular forces, the higher is boiling point of compound, because more energy is needed to break interaction between molecules.
There are several types of intermolecular forces: hydrogen bonding, ion-induced dipole forces, ion-dipole forces andvan der Waals forces.
