Which species among the following doesn't show disproportionation reactions?
Options
- A( ClO ₂⁻ )
- B( ClO ₃⁻ )
- C( ClO ⁻ )
- D( ClO ₄⁻ )
Correct answer
D. ( ClO ₄⁻ )
Step-by-step solution
Disproportionation is a specific type of redox reaction in which a species is simultaneously reduced and oxidised to form two different products. Electronic configuration of ( Cl ) is (1 s^2 2 s^2 2 p^6 3 s^2 3 p^5 ) It can exhibit an maximum oxidation state of +7. In the given question, All species can exhibit disproportionation reaction which simultaneously oxidise as well as reduce. In ( ClO ₄⁻ )this cannot undergo oxidation as +7 is maximum oxidation state exhibited by chlorine. Hence, the correct option is (d)
