Suitable reducing agent for aldehyde is:
Correct answer: B. NaBH4
- A. Na2CO3
- B. NaBH4
- C. KMnO4
- D. NaBH2
Explanation
A suitable reducing agent for aldehydes is sodium borohydride (NaBH4) or lithium aluminum hydride (LiAlH4). These reducing agents are commonly used in organic chemistry to convert aldehydes into primary alcohols through a reduction reaction. Sodium borohydride (NaBH4) is milder and is often used for the reduction of aldehydes under mild conditions, making it suitable for reactions that need to be carried out in aqueous or alcoholic solutions. Therefore, option b 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.
