प्रश्न

Arrange the following in increasing order of boiling points:

(CH3)3 N, C2 H5 OH, C2 H5 NH2

टिप्पणी लिखिए

उत्तर

This increasing order of boiling points can be explained by intermolecular hydrogen bonding. Tertiary amines, cannot engage in hydrogen bonding because they have no hydrogen atom bonded to the nitrogen atom, while primary amine undergoes intermolecular hydrogen bonding. But in the case of alcohol, the extent of hydrogen bonding is more as compared to amines because of a more electronegative oxygen atom in alcohol.
(CH3)3N<C2H5NH2<C2H5OH
