Acetone is less reactive than acetaldehyde due to:
Correct answer: A. More stearic hindrance offered by its methyl groups
- A. More stearic hindrance offered by its methyl groups
- B. Electron withdrawing nature of its methyl groups
- C. Its carbonyl carbon is sp2 hybridized
- D. Oxygen of carbonyl group is more electronegative than carbon atom
Explanation
Acetone is less reactive towards nucleophilic addition reaction as compared to acetaldehyde due to greater I-effect of the two alkyl group and also greater Stearic hindrance offered to the attacking nucleophile.

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.
