In disproportionation reactions, same element undergoes oxidation as well as reduction. Among the given reaction, reaction (d) is a disproportionation reaction. <img class="img-fluid question-image" alt="image" src="https://cdn.tardigrade.in/img/question/chemistry/989db0d647b1103902290ab93340e96c-.png" /> Here, CuBr get oxidised to CuBr 2 and also it get reduced to Cu.

Q. An example of a disproportionation reaction is

$2 M n O_{4}^{-} + 10 I^{-} + 16 H^{+} ⟶ 2 M n^{2 +} + 5 I_{2} + 8 H_{2} O$

$2 N a B r + C l_{2} ⟶ 2 N a Cl + B r_{2}$

$2 K M n O_{4} ⟶ K_{2} M n O_{4} + M n O_{2} + O_{2}$

$2 C u B r ⟶ C u B r_{2} + C u$

In disproportionation reactions, same element undergoes oxidation as well as reduction.
Among the given reaction, reaction (d) is a disproportionation reaction.

Here, $C u B r$ get oxidised to $C u B r_{2}$ and also it get reduced to $C u$ .
