Indusstrially, `H_(2)O_(2)` is obtainned by the following cyclic process:
`underset((P))("2-Ethylanthraquinol") underset(H_(2)//Pd)overset(O_(2))hArr underset((Q))("2-Ethylathraquinone")+H_(2)O_(2)`
Which one of the followin properties is wrong about the mixture of organic solvents inwhich the reaction is carried out?

Options

A. It must resist oxidation
B. it must be miscible with water.
C. It must dissolve both (P) and (Q)
D. It is generally a mixture of ester and hydrocarbon.

Answer

To solve the problem, we need to analyze the properties of the organic solvent mixture used in the industrial process of obtaining hydrogen peroxide (H₂O₂) from 2-Ethylanthraquinol and 2-Ethylanthraquinone.

### Step-by-Step Solution:

1. **Understanding the Reaction:**
The cyclic process involves the reduction of 2-Ethylanthraquinone (Q) to 2-Ethylanthraquinol (P) using hydrogen (H₂) in the presence of palladium (Pd), followed by the oxidation of P back to Q with oxygen (O₂), producing H₂O₂ as a byproduct.

2. **Analyzing the Properties of the Organic Solvent Mixture:**
We need to evaluate the four given properties of the organic solvent mixture in which the reaction occurs:
- **Option A:** It must resist oxidation.
- **Option B:** It must be miscible with water.
- **Option C:** It must dissolve both P and Q.
- **Option D:** It is generally a mixture of ester and hydrocarbon.

3. **Evaluating Each Option:**
- **Option A:** The solvent must resist oxidation because we want to oxidize P (2-Ethylanthraquinol) to Q (2-Ethylanthraquinone) without the solvent itself undergoing oxidation. This property is correct.
- **Option B:** The solvent must be miscible with water. However, since H₂O₂ is produced and needs to be separated, the solvent should not be miscible with water. This property is incorrect.
- **Option C:** The solvent must dissolve both P and Q. For the reaction to proceed effectively, the solvent must be able to dissolve both reactants and products. This property is correct.
- **Option D:** The solvent is generally a mixture of ester and hydrocarbon. This is a plausible property as esters can be polar and hydrocarbons non-polar, which can facilitate the reaction. This property is correct.

4. **Identifying the Incorrect Property:**
From the analysis, we find that **Option B** is the incorrect statement because the organic solvent mixture should not be miscible with water to allow for the separation of H₂O₂.

### Final Answer:
The incorrect property about the mixture of organic solvents in which the reaction is carried out is **Option B: It must be miscible with water.**
