Amines are reactive due to the difference in electronegativity between nitrogen and hydrogen, as well as the presence of an unshared pair of electrons on the nitrogen atom. The number of hydrogen atoms attached to nitrogen determines the course of ...

The order of boiling points for isomeric amines is Primary > Secondary > Tertiary. Boiling points of amines, alcohols, and alkanes with similar molar masses generally follow the trend Amines > Alcohols > Alkanes.

Tertiary amines lack intermolecular association as they do not have hydrogen atoms available for hydrogen bond formation. Consequently, the order of boiling points among isomeric amines is Primary > Secondary > Tertiary.

Intermolecular association in primary and secondary amines is due to hydrogen bonding between the nitrogen of one molecule and the hydrogen of another. Primary amines exhibit stronger association because they have two hydrogen atoms available for hydrogen bond formation.

Butan-1-ol is expected to be more soluble in water than butan-1-amine because alcohols form stronger intermolecular hydrogen bonds with water compared to amines.
