Hybridization of carbon in -CHO group is:
Correct answer: B. sp2
- A. sp
- B. sp2
- C. sp3
- D. dsp
Explanation
In the CHO group, - HC=O, the carbon is double bonded to an oxygen and single bonded to hydrogen and another R group, which may be an alkyl or some other group. It has no lone pairs remaining. In other words, the central atom Carbon is bonded to three other groups only. Therefore the hybridisation that it corresponds to is sp2, as can be confirmed from the table below:

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.
