The reduction potential values of M, N and O are +2.46 V, -1.13 V, -3.13 V respectively. Which of the following orders is correct regarding their reducing property ?

Options

A. `O gt N gt M`
B. `O gt M gt N`
C. `M gt N gt O`
D. `M gt O gt N`

Answer

To determine the correct order of reducing properties for the elements M, N, and O based on their reduction potential values, we can follow these steps:

### Step 1: Understand Reduction Potential
Reduction potential indicates the tendency of a species to gain electrons (be reduced). A higher reduction potential means a stronger oxidizing agent, while a lower reduction potential indicates a stronger reducing agent.

### Step 2: List the Given Reduction Potentials
The reduction potentials for the elements are:
- M: +2.46 V
- N: -1.13 V
- O: -3.13 V

### Step 3: Analyze the Reduction Potentials
From the values:
- M has the highest reduction potential (+2.46 V), meaning it is the strongest oxidizing agent and the weakest reducing agent.
- N has a moderate reduction potential (-1.13 V), indicating it is a weaker oxidizing agent than M but stronger than O.
- O has the lowest reduction potential (-3.13 V), indicating it is the weakest oxidizing agent and the strongest reducing agent.

### Step 4: Determine the Reducing Property Order
Since reducing property is inversely related to reduction potential:
- O (most reducing) > N > M (least reducing)

### Conclusion
The correct order regarding their reducing property is:
**O > N > M**
