Mark the Incorrect statement about aldehydes and ketones
Correct answer: D. Aldehydes have H-bonding but ketones do not have
- A. They have higher boiling points than that of alkalies
- B. Theyhave lower boiling points than that of alcohols
- C. They have higher boiling point than resulting camphor.
- D. Aldehydes have H-bonding but ketones do not have
Explanation
This statement OPTION D is generally correct. Aldehydes can participate in hydrogen bonding because they have a hydrogen atom directly bonded to the carbonyl carbon. Ketones, lacking this specific hydrogen, exhibit weaker dipole-dipole interactions compared to aldehydes. While ketones can exhibit dipole-dipole interactions, they typically do not engage in hydrogen bonding to the same extent as 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.
