प्रश्न
Give reason for the following:
Primary amines have higher boiling point than tertiary amines.
Account for the following:
Primary amines (R-NH2) have higher boiling point than tertiary amines (R3N).
उत्तर
Primary amines exhibit intermolecular hydrogen bonding, necessitating greater energy to disrupt the attraction. In tertiary amines, intermolecular hydrogen bonding is absent.
