- In Aldehydes and Ketones, the carbonyl carbon and oxygen atoms are sp2Â hybridized. This indicates that group attached to the carbon atom and oxygen are present in a plane.
- There is electronegativity difference between carbon and oxygen so the bond between carbon and oxygen has a significant dipole moment.
- 1.The Polar nature of the carbonyl group makes the oxygen atom nucleophilic and basic while carbon atom behaves as an electrophile.
- This dipole-dipole attraction between the molecules of aldehydes and ketones results in higher boiling points.
- Although pure ketones and aldehydes cannot engage in hydrogen bonding with each other, they have lone pairs of electrons and can act as hydrogen bond acceptors with other compounds have O – H or N – H bonds.
- These compounds are water soluble because they can form hydrogen bonding with water molecules. Because of this hydrogen bonding, ketones and aldehydes are good solvents for polar hydroxylic substances such as alcohols.
