The carbonyl carbon in aldehydes and ketones is:
Correct answer: B. sp² hybridized
- A. sp hybridized
- B. sp² hybridized
- C. sp³ hybridized
- D. unhybridized
Explanation
The carbon atom in a carbonyl group (C=O) forms three sigma bonds and one pi bond. This bonding arrangement corresponds to sp² hybridization, resulting in a trigonal planar geometry around the carbon atom.

About Aldehydes and Ketones
Aldehydes and ketones contain the polar carbonyl group, but aldehydes are generally more readily oxidised and more reactive than ketones. Coverage includes preparation by oxidation or reduction routes, nucleophilic addition of reagents such as hydrogen cyanide and bisulfite, and tests that distinguish aldehydes from ketones.
