Which of the following isomers has highest boiling point?
Which of the following isomers has highest boiling point?
tert-Butylamine
Ethyldimethylamine
Diethylamine
n-Butylamine
Solution
Based on the extent of the intermolecular forces the observed order of boiling points of isomeric amines is: primary amine $\gt$ secondary amine $\gt$ tertiary amine.
Hence, n-butyl amine has the highest boiling point.
