Answer:
H2O > CH3OH > CH3CH2NH2 > CH3OCH3 > CH3CH2CH3
Explanation:
Hydrogen bonding exists in molecules in which hydrogen is bonded to a highly electronegative element such as fluorine, chlorine, oxygen, sulphur, nitrogen etc.
Water has the highest degree of hydrogen bonding among the listed substances hence its very high boiling point, stemming from intermolecular hydrogen bonding. CH3CH2NH2 has a lesser degree of hydrogen bonding because nitrogen is less electronegative than oxygen.
Alcohols show significant hydrogen bonding in solution, the same applied to amines. However, ethers do not form hydrogen bonds with each other but they can form hydrogen bonds with other molecules such as alcohols and amines. Alkanes do not form hydrogen bonds at all.
