In all these reactions the same substance is reduced as well as oxidised.

Q. Which of the following represents a disproportionation reaction ?

$C l_{2} + 2 O H^{-} \to Cl O^{-} + C l^{-} + H_{2} O$

$C u_{2} O + H^{+} \to C u^{2 +} + O H^{-}$

$2 H C u C l_{2} dilution with H_{2} O C u + C u^{2 +} + 4 C I^{-} + 2 H^{+}$

All the three above
