Arrange the following in the increasing order of their boiling point: C2H5NH2, C2H5OH, (CH3)3N

Increasing order of boiling point: (CH3)3N < C2H5NH2 < C2H5OH

Alcohols have a higher boiling point as compared to that of amines because of oxygen, being more electronegative, forms strong hydrogen bond as compared to that of nitrogen. In tertiary amine, there is no hydrogen to form hydrogen bond and hence, has the lowest boiling point.
