Understanding Aldehyde Oxidation
Aldehydes are organic compounds characterized by the presence of a carbonyl group (C=O) bonded to at least one hydrogen atom. The oxidation of aldehydes leads to the formation of carboxylic acids, which is a key transformation in organic chemistry.
Oxidation Process
- Oxidizing Agents: Aldehydes can be oxidized by various agents such as potassium permanganate (KMnO4), dichromate (K2Cr2O7), or even atmospheric oxygen.
- Conversion: During oxidation, the hydrogen atom attached to the carbonyl carbon is removed, and an additional oxygen atom is added, resulting in the formation of a carboxylic acid (RCOOH).
Why Other Options Are Incorrect
- Reduction (Option A): This process involves the addition of hydrogen or removal of oxygen, which would convert aldehydes into primary alcohols, not acids.
- Hydrolysis (Option B): This is a reaction with water that typically affects esters or amides rather than aldehydes, and does not yield carboxylic acids directly.
- Hydrogenation (Option C): Involves the addition of hydrogen to a compound, reducing aldehydes to alcohols rather than oxidizing them to acids.
Conclusion
The correct pathway for converting aldehydes to carboxylic acids is through oxidation. This transformation is fundamental in organic synthesis and plays a significant role in various chemical reactions. Thus, option 'D' is the correct answer, highlighting the importance of understanding oxidation in organic chemistry.

When an aldehyde is oxidised, the product formed is a carboxylic acid.
Key points to understand this process:
  • Oxidation involves the addition of oxygen or the removal of hydrogen.
  • Aldehydes are converted to carboxylic acids through oxidation.
  • Common oxidising agents include alkaline potassium permanganate and acidified potassium dichromate.
These agents facilitate the transformation by providing the necessary conditions for the reaction.
