Which of the following species, do not show disproportionation reaction and why ?
`ClO^(-) , ClO_(2)^(-) , ClO_(3)^(-) ` and `ClO_(4)^(-)`
Also write reaction for each of the species that disproportionates.

Explanation

To determine which of the given species do not show disproportionation reactions, we need to analyze the oxidation states of chlorine in each species and see if they can undergo both oxidation and reduction.

### Step 1: Analyze the oxidation states of chlorine in each species

1. **For ClO⁻**:
- Let the oxidation state of Cl be \( x \).
- The equation becomes: \( x + 2(-2) = -1 \)
- Solving gives: \( x - 4 = -1 \) → \( x = +1 \)
