Bulky ketones do not react with
Correct answer: A. Sodium bisulphite
- A. Sodium bisulphite
- B. HCI
- C. Grignard reagent
- D. HCN
Explanation
The reason why bulky ketones do not react with sodium bisulphite is because the bulky groups on the ketone make it difficult for the sodium bisulphite to approach the carbonyl group. The sodium bisulphite is a nucleophile, and it needs to be able to approach the carbonyl group in order to react with it. Therefore, option a is correct.

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.
