A reaction in which the same species is simultaneously oxidised as well as reduced is called a disproportionation reaction. <img class="img-fluid question-image" alt="image" src="https://cdn.tardigrade.in/img/question/chemistry/cc81111468206315c3b59b2ff58fcac7-.png" />

Q. Which one of the following is an example of disproportionation reaction?

$3 C l_{2} (g) + 6 O H^{-} (a q) ⟶ Cl O_{3}^{-} (a q) + 5 C l^{-} (a q) + 3 H_{2} O (l)$

$A g^{2 +} (a q) + A g (s) ⟶ 2 A g^{+} (a q)$

$Z n (s) + C u S O_{4} (a q) ⟶ C u (s) + Z n S O_{4} (a q)$

$2 K Cl O_{3} (s) ⟶ 2 K Cl (s) + 3 O_{2} (g)$
