The correct statement(s) regarding hydrates of aldehyde and ketone is/...
Hydrates of aldehydes and ketones are less stable than anhydrous form (gem diols are unstable).
Hydrates form H-bonds with water, hence hydrate content is more in water than in hexane.
This exchange occur via hydrate.

The correct statement(s) regarding hydrates of aldehyde and ketone is/...
Hydrates of Aldehyde and Ketone:
1. Thermodynamic Stability:
- Usually, hydrates have lower thermodynamic stability than the anhydrous form.
- The presence of water in the structure of aldehydes and ketones affects their stability and reactivity.
- The formation of hydrates is an equilibrium process, and the stability of the hydrate depends on the balance between the hydration energy and the energy required to break the water-aldehyde or water-ketone interactions.
- In most cases, the anhydrous form is more stable than the corresponding hydrate.
2. Hydrate Content of Acetone:
- The hydrate content of acetone is greater in water than in hexane.
- Acetone (CH3COCH3) is a ketone that readily forms hydrates in the presence of water.
- In an aqueous environment, water molecules can interact with the carbonyl oxygen of acetone through hydrogen bonding, leading to the formation of hydrates.
- Hexane, on the other hand, is a non-polar solvent and does not readily form hydrates with acetone.
3. Isotopic Labeling:
- When CH3CHO (acetaldehyde) is treated with H2O18 (water containing the stable isotope oxygen-18) in acidic medium, it gets converted into CH3CHO18.
- This reaction is an example of isotopic labeling, where a specific atom or group of atoms is replaced with its isotopic counterpart.
- The acidic medium helps in the protonation of the carbonyl oxygen, making it more susceptible to nucleophilic attack by water molecules containing oxygen-18.
- The resulting product, CH3CHO18, contains the oxygen-18 isotope, which can be used for various studies and analyses.
4. Hydrate Content of C6H5CHO and p-nitrobenzaldehyde:
- C6H5CHO (benzaldehyde) and p-nitrobenzaldehyde both can form hydrates, but C6H5CHO has a greater hydrate content than p-nitrobenzaldehyde.
- The hydrate content depends on the ability of the aldehyde or ketone to form hydrogen bonds with water molecules.
- Benzaldehyde (C6H5CHO) has a phenyl group attached to the carbonyl carbon, which enhances its ability to form hydrogen bonds with water, leading to a higher hydrate content.
- In contrast, p-nitrobenzaldehyde has a nitro group (-NO2) attached to the carbonyl carbon, which reduces its ability to form hydrogen bonds with water, resulting in a lower hydrate content compared to benzaldehyde.
Therefore, the correct statements regarding hydrates of aldehyde and ketone are A) Usually hydrates have lower thermodynamic stability than the anhydrous form, B) Hydrate content of acetone is greater in water than in hexane, and C) CH3CHO when treated with H2O18 in acidic medium gets converted into CH3CHO18.

- In most cases, the anhydrous form is more stable than the corresponding hydrate.

- C6H5CHO (benzaldehyde) and p-nitrobenzaldehyde both can form hydrates, but C6H5CHO has a greater hydrate content than p-nitrobenzaldehyde.
- The hydrate content depends on the ability of the aldehyde or ketone to form hydrogen bonds with water molecules.

- In contrast, p-nitrobenzaldehyde has a nitro group (-NO2) attached to the carbonyl carbon, which reduces its ability to form hydrogen bonds with water, resulting in a lower hydrate content compared to benzaldehyde.
Therefore, the correct statements regarding hydrates of aldehyde and ketone are A) Usually hydrates have lower thermodynamic stability than the anhydrous form, B) Hydrate content of acetone is greater in water than in hexane, and C) CH3CHO when treated with H2O18 in acidic medium gets converted into CH3CHO18.
