Arrange the amines in order of increasing boiling point (lowest first).
Methylamine ethylamine propylamine cyclohexylamine
I II III IV

Question

Quizplus · Accepted Answer

The boiling point of amines increases with increasing molecular weight due to the increase in van der Waals forces. Cyclohexylamine, being a cyclic and bulkier molecule, has a higher boiling point due to its larger surface area, which allows for stronger van der Waals interactions compared to the straight-chain amines. Therefore, the order from lowest to highest boiling point is methylamine (I), ethylamine (II), propylamine (III), and cyclohexylamine (IV).
