Aldehydes have higher boiling points than alkanes of similar molecular weight, give suitable reasons. |
Answer» Solution :The carbonyl group in aldehyde is polar in NATURE.  As a result, the molecules of ALDEHYDES are held together by strong dipole-dipole attractions. Hence, large amount of energy is REQUIRED to overcome these attractive interaction. Such kind of ATTRACTION is not PRESENT in alkanes. Therefore aldehydes have higher boiling points than the corresponding alkanes. |
