Which of the following examples does not represent disproportionation ?

A

`MnO_(2) + 4HCl to MnCl_(2) + Cl_(2) + 2H_(2)O`

B

`2H_(2)O_(2) to 2H_(2)O + O_(2)`

C

`4KClO_(3) to 3KClO_(4) + KCl`

D

`3Cl_(2) + 6NaOH to 5NaCl + NaClO_(3) + 3H_(2)O`

Text Solution

Verified by Experts

The correct Answer is:
A
In A) reaction, oxidation state of chlorine changes from -1 in HCl to 0 in `Cl_(2)` and `-1` in `MnCl_(2)`.
Here chlorine undergoes only oxidation. So this is not disproportionation
