Identifity disporportionation reaction

Options

A. `CH_4 + 2O_2 to CO_2 + 2H_2O`
B. `CH_4 + 4Cl_2 to C Cl_4 + 4HCl`
C. `2F_2 +2OH^(-) to 2F^(-) + OF_2 + H_2O`
D. `2NO_2 + 2OH^(-1) to NO_2 ^(-) + NO_3^(-) + H_2O`

Explanation

To identify a disproportionation reaction, we need to understand that it involves a single substance undergoing both oxidation and reduction simultaneously. Here’s a step-by-step solution to identify a disproportionation reaction:

### Step-by-Step Solution:

1. **Understand the Definition**: A disproportionation reaction is a type of redox reaction where one element is both oxidized and reduced. This means that in the reaction, the same element changes its oxidation state to a higher (oxidation) and a lower (reduction) state.

2. **Examine the Given Reactions**: Look at the reactions provided. You need to analyze the oxidation states of the elements involved in each reaction.
