Correct answer is (c) 2 CuBr longrightarrow CuBr 2+ Cu

Q. An example of a disproportionation reaction is :

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

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

$2 C u B r ⟶ C u B r_{2} + C u$

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

Correct answer is (c) $2 C u B r ⟶ C u B r_{2} + C u$

Q. An example of a disproportionation reaction is :

2KMnO4​⟶K2​MnO4​+MnO2​+O2​

2MnO4​−+10I−+16H+⟶2Mn2++5I2​+8H2​O

2CuBr⟶CuBr2​+Cu

2NaBr+Cl2​⟶2NaCl+Br2​

Correct answer is (c) 2CuBr⟶CuBr2​+Cu

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

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

$2 C u B r ⟶ C u B r_{2} + C u$

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

Correct answer is (c) $2 C u B r ⟶ C u B r_{2} + C u$
