An aldehyde on oxidation gives

Options

A. An alcohol
B. An acid
C. A ketone
D. An ether

Answer

**Step-by-Step Solution:**

1. **Understanding Aldehydes**: Aldehydes are organic compounds that contain a carbonyl group (C=O) with at least one hydrogen atom attached to the carbon. The general formula for an aldehyde is RCHO, where R is a hydrocarbon group.

2. **Oxidation of Aldehydes**: When aldehydes undergo oxidation, they can be converted into carboxylic acids. This is because the carbonyl carbon in the aldehyde can be further oxidized to form a carboxylic acid (RCOOH).

3. **Identifying the Reaction**: The oxidation of an aldehyde can be represented by the following chemical equation:
\[ RCHO + [O] \rightarrow RCOOH \]
Here, [O] represents an oxidizing agent, which could be oxygen or another oxidizing compound.

4. **Conclusion**: Therefore, when an aldehyde is oxidized, the product formed is a carboxylic acid.

**Final Answer**: An aldehyde on oxidation gives a carboxylic acid (RCOOH).
