2-Ethyl anthraquinol when oxidised in air produces

Options

A. `O_(3)`
B. `H_(2)O_(2)`
C. `H_(2)O`
D. `C_(2)H_(5)OH`

Answer

To solve the question regarding the oxidation of 2-Ethyl anthraquinol in air, we can follow these steps:

### Step 1: Understand the Structure
2-Ethyl anthraquinol is a derivative of anthraquinone, where an ethyl group is attached to the second position of the anthraquinol structure. The structure consists of three fused benzene rings with two hydroxyl (OH) groups.

**Hint:** Familiarize yourself with the structure of anthraquinol and the position of the substituents.

### Step 2: Identify the Oxidation Reaction
When 2-Ethyl anthraquinol is oxidized, it reacts with oxygen (O2) from the air. The hydroxyl groups (-OH) on the anthraquinol can be oxidized to form carbonyl groups (C=O), leading to the formation of anthraquinone.

**Hint:** Recall that oxidation typically involves the loss of hydrogen or the gain of oxygen.

### Step 3: Determine the Products
Upon oxidation, the two hydroxyl groups of 2-Ethyl anthraquinol are converted into carbonyl groups, resulting in the formation of 2-Ethyl anthraquinone. Additionally, during this oxidation process, hydrogen peroxide (H2O2) is also produced as a byproduct.

**Hint:** Remember that the oxidation of alcohols can lead to the formation of ketones or aldehydes, depending on the structure.

### Step 4: Conclusion
The main product of the oxidation of 2-Ethyl anthraquinol in air is 2-Ethyl anthraquinone, and hydrogen peroxide is produced as a byproduct. Therefore, the answer to the question is that 2-Ethyl anthraquinol when oxidized in air produces hydrogen peroxide.

**Final Answer:** 2-Ethyl anthraquinol when oxidized in air produces hydrogen peroxide.
