Benzaldehyde can be oxidised to corresponding carboxylate anion with

Options

A. Fehling's reagent
B. Tollen's reagent
C. Both Fehling's and Tollen's reagent
D. Neither Fehling's nor Tollen's reagent

Answer

To solve the question regarding the oxidation of benzaldehyde to the corresponding carboxylate anion, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Compound**:
- Benzaldehyde (C₇H₆O) is an aromatic aldehyde.

2. **Understand the Reaction**:
- The oxidation of benzaldehyde involves converting the aldehyde functional group (-CHO) into a carboxylate ion (RCOO⁻).

3. **Select the Oxidizing Agent**:
- To oxidize benzaldehyde, we need a suitable oxidizing agent. Mild oxidizing agents are preferred for this reaction.

4. **Consider Common Oxidizing Agents**:
- Common oxidizing agents include Tollen's reagent, Benedict's reagent, and Fehling's solution. However, not all of these can oxidize aromatic aldehydes.

5. **Evaluate the Options**:
- Tollen's reagent (Ag(NH₃)₂⁺) is a mild oxidizing agent that can oxidize benzaldehyde to benzoate ion.
- Fehling's solution and Benedict's reagent are not effective for aromatic aldehydes like benzaldehyde.

6. **Conclusion**:
- The appropriate oxidizing agent for converting benzaldehyde to the corresponding carboxylate anion is Tollen's reagent.

### Final Answer:
Benzaldehyde can be oxidized to the corresponding carboxylate anion with Tollen's reagent.
