Arrange the Following in Increasing Order of Boiling Points: (Ch3)3 N, C2 H5 Oh, C2h5nh2 - Chemistry


Short Note

Arrange the following in increasing order of boiling points:

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


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.
