Ketones are less reactive than aldehydes. It is because of the following reasons EXCEPT:
Correct answer: A. Both alkyl groups are more electron-donating than that of aldehyde
- A. Both alkyl groups are more electron-donating than that of aldehyde
- B. Both alkyl groups produce more steric hindrance
- C. Both alkyl group decrease more polarity of carbonyl groups of ketone
- D. Both alkyl groups are electron-withdrawing groups and increase polarity
Explanation
a. Both alkyl groups are more electron donating than that of aldehyde - This statement is incorrect. Alkyl groups are electron donating and can increase the reactivity of carbonyl compounds. However, this is not the reason why ketones are less reactive than aldehydes.

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.
