Question

2CuI →Cu + CuI_2.This reaction is

Easy

A

Disproportionation reaction
B

Neutralization reaction
C

Oxidation reaction
D

Reduction reaction

Solution

Reaction in which same element undergoes simultaneously both oxidation and reduction is disproportionation reaction
In the given reaction oxidation state of Cu is decreased from +1 to zero and also increased from +1 to +2.
$2 \overset{+ 1}{Cu} I \to \overset{0}{Cu} + \overset{+ 2}{Cu} I_{2};$
