Treatment of tartaric acid with Fenton's reagent gives :

Options

A. Pyruvic acid
B. Maleic acid
C. Tartaric anhydride
D. Dihydroxyfurmaric acid

Explanation

To solve the question regarding the treatment of tartaric acid with Fenton's reagent, we can follow these steps:

### Step 1: Understand the Reactants
- **Tartaric Acid**: Tartaric acid is a naturally occurring organic acid with the formula C4H6O6. It contains two carboxylic acid groups (-COOH) and two hydroxyl groups (-OH).
- **Fenton's Reagent**: Fenton's reagent consists of ferrous iron (Fe²⁺) and hydrogen peroxide (H₂O₂). It is known for its ability to oxidize organic compounds.

### Step 2: Analyze the Reaction
- When tartaric acid is treated with Fenton's reagent, the ferrous ion (Fe²⁺) and hydrogen peroxide (H₂O₂) will facilitate the oxidation of tartaric acid.
- The reaction involves the removal of hydrogen atoms, leading to the formation of double bonds in the structure of tartaric acid.

### Step 3: Identify the Product
- The oxidation process will convert tartaric acid into a compound that has double bonds due to the removal of hydrogen atoms.
- The resulting compound will have two hydroxyl groups and a double bond, which corresponds to the structure of dihydroxyfumaric acid.

### Step 4: Conclusion
- The final product formed from the reaction of tartaric acid with Fenton's reagent is **dihydroxyfumaric acid**.

### Final Answer
The treatment of tartaric acid with Fenton's reagent gives **dihydroxyfumaric acid**.
