The reactions, in which the same element is oxidized as well as reduced, are called disproportionation reactions.
In this reaction, the same element, ie,

C l_{2}

is oxidized as well as reduced, so it is an example of disproportionation reaction.

Q. Which one of the following reactions involves disproportionation?

$2 H_{2} S O_{4} + C u C u S O_{4} + 2 H_{2} O + S O_{2}$

$A s_{2} O_{3} + 3 H_{2} S A s_{2} S_{3} + 3 H_{2} O$

$2 K O H + C l_{2} K Cl + K OCl + H_{2} O$

$C a_{3} P_{2} + 6 H_{2} O 3 C a (O H)_{2} + 2 P H_{3}$

$4 N H_{3} + 3 O_{2} 2 N_{2} + 6 H_{2} O$
