Identify the disproportionation reaction.

A

`CH_4+2O_2 rarr CO_2+2H_2O`

B

`CH_4+4Cl_2 rarr " CCl"_4+4HCl`

C

`2F_2+2OH^(-) rarr 2F^(-) +OF_2+H_2O`

D

`2NO_2+2OH ^(-) rarr NO_2^(-)+NO_3^(-) +H_2O`

Text Solution

Verified by Experts

The correct Answer is:
D
`2NO_2+2OH^(-) rarr NO_2^(-) +NO_3^(-) +H_2O` is a disproportionaton reaction because N is both oxidised as well as reduced ,O.N. of N increases from +4 (in `NO_2` ) to +3 (in `NO_2^(-)` )
