Amines exhibit basic character by reacting with acids to form salts. Amine salts, soluble in water but insoluble in organic solvents like ether, can be regenerated to the parent amine when treated with a base such as NaOH.

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.
