Find the incorrect statement

Options

A. Higher reduction potential of non-metal means stronger reducing agent
B. Lower oxidation potential of a metal means weak oxidising agent
C. Oxidation state of oxygen in `O_(3)` is -1
D. All of these

Answer

To solve the question of identifying the incorrect statement among the given options, we will analyze each statement one by one.

### Step-by-Step Solution:

1. **Understanding Reducing Agents and Reduction Potential**:
- A reducing agent is a substance that donates electrons to another substance and gets oxidized in the process.
- The reduction potential indicates the tendency of a species to gain electrons (be reduced). A higher reduction potential means a stronger tendency to be reduced.

2. **Analyzing Option 1**:
- The statement claims: "Higher reduction potential of non-metal means stronger reducing agent."
- Since a higher reduction potential indicates a stronger oxidizing agent (not a reducing agent), this statement is incorrect.

3. **Analyzing Option 2**:
- The statement claims: "Lower oxidation potential of a metal means weak oxidizing agent."
- A lower oxidation potential corresponds to a higher reduction potential, which means a stronger oxidizing agent. Therefore, this statement is also incorrect.

4. **Analyzing Option 3**:
- The statement claims: "Oxidation state of oxygen in O3 is -1."
- Ozone (O3) consists of three oxygen atoms. In ozone, the oxidation state of each oxygen atom is actually 0 due to the lack of electronegativity difference among the same atoms. Thus, this statement is incorrect as well.

5. **Conclusion**:
- All three options (1, 2, and 3) are incorrect. Therefore, the answer to the question is option 4, which states that all of the above options are incorrect.

### Final Answer:
All of the statements (1, 2, and 3) are incorrect.
