Class 12 Chemistry Aldehydes, Ketones & Carboxylic Acid – Important Topics

Carbonyl compounds are those compounds that contain a carbon-oxygen double bond in them. Aldehydes, Ketones and Carboxylic acids are carbonyl compounds as they have C=O group in them.

• The carbon atom of the carbonyl compound is an sp²-hybridized atom. It forms 3 sigma bonds. 
• The fourth valence electron remains in the p-orbital.
• Carbonyl compounds forms a Pi bond with the oxygen by overlapping with the p-orbital of the oxygen atom. 
• The bond angle of the carbonyl compound is around 120 degrees.
• The carboxyl carbon bonds of the carboxylic acid lie on one plane. 
• The carboxylic carbon has less electrophilic property than the carbonyl compound due to resonating structures.
