Ketones are less reactive in nucleophilic substitution because:
Correct answer: D. Option D
- A. Option A
- B. Option B
- C. Option C
- D. Option D
Explanation
Ketones are indeed less reactive in nucleophilic substitution reactions compared to aldehydes. One of the reasons for this is that ketones have an electron-donating environment around the carbon-oxygen double bond. This electron-donating effect makes it harder for nucleophiles to attack the carbon atom in the ketone molecule. In contrast, aldehydes have a more electron-withdrawing environment, which makes them more reactive towards nucleophilic substitution. This difference in reactivity is due to the presence of the additional alkyl group in ketones, which stabilizes the molecule and reduces its reactivity.

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.
