Statement - 2 : Oxygen has -2 oxidation state in `H_(2)`O

Options

B. If both the statements are True and statement-2 is not the correct explanation of statement-1
C. If statement-1 is true and statement-2 is False.
D. If statement-1 is false and statement-2 is True.

Answer

To analyze the given statements and determine their correctness, we will follow these steps:

### Step 1: Analyze Statement 1
**Statement 1:** `2H2O2 → 2H2O + O2` is a decomposition reaction (Redox).

1. **Identify the Reaction Type:**
- The reaction involves the breakdown of hydrogen peroxide (H2O2) into water (H2O) and oxygen (O2). This is indeed a decomposition reaction as it involves the breakdown of a single compound into two products.

2. **Determine if it is a Redox Reaction:**
- To classify it as a redox reaction, we need to check the oxidation states of the elements involved.
- In H2O2, the oxidation state of oxygen is -1 (since it is in the peroxide form).
- In H2O, the oxidation state of oxygen is -2.
- In O2, the oxidation state of oxygen is 0.
- The oxidation state of hydrogen remains +1 in both H2O2 and H2O.

3. **Change in Oxidation States:**
- Oxygen changes from -1 in H2O2 to -2 in H2O (reduction) and from -1 in H2O2 to 0 in O2 (oxidation).
- Since there is a change in oxidation states, this reaction is indeed a redox reaction.

**Conclusion for Statement 1:** The statement is true; it is a decomposition reaction and also a redox reaction.

### Step 2: Analyze Statement 2
**Statement 2:** Oxygen has -2 oxidation state in H2O.

1. **Determine the Oxidation State of Oxygen in H2O:**
- In water (H2O), the oxidation state of oxygen is indeed -2.
- Hydrogen has an oxidation state of +1, and with two hydrogen atoms, the total positive charge is +2.
- To balance this, oxygen must have a -2 oxidation state to ensure the overall charge is neutral.

**Conclusion for Statement 2:** The statement is true; oxygen does have a -2 oxidation state in H2O.

### Final Conclusion
- **Statement 1:** True (it is a decomposition reaction and a redox reaction).
- **Statement 2:** True (oxygen has -2 oxidation state in H2O).

### Answer
Both statements are true.
