Question

Give plausible explanation for: Why do primary amines have higher boiling points than tertiary amines?

Answer 1

Primary amines are engaged in intermolecular association due to hydrogen bonding between nitrogen of one and hydrogen of another molecule.

Tertiary amines do not have intermolecular associations due to the absence of hydrogen atom available for hydrogen bond formation.

Therefore, primary amines have higher boiling points than tertiary amines.
