Question
Arrange the following compounds in increasing order of their boiling points:
CH3CH2OH, CH3−CHO, CH3−COOH
Advertisements
Solution
The increasing order of boiling point in the following compounds is CH3−CHO < CH3CH2OH < CH3−COOH. Ethanoic acid and ethanol have a comparatively higher boiling point than ethanal, as they both are held by strong hydrogen bonds in between them, whereas in ethanal there is a dipole-dipole interaction between them.
