Identify disproportionation reaction.

A) \[C{{H}_{3}}+2{{O}_{2}}\xrightarrow{{}}C{{O}_{2}}+2{{H}_{2}}O\]

B)  \[C{{H}_{4}}+4C{{l}_{2}}\xrightarrow{{}}CC{{l}_{4}}+4HCl\]

C)  \[2{{F}_{2}}+2O{{H}^{-}}\xrightarrow{{}}2{{F}^{-}}+O{{F}_{2}}+{{H}_{2}}O\]

D)  \[2N{{O}_{2}}+2O{{H}^{-}}\xrightarrow{{}}NO_{2}^{-}+NO_{3}^{-}+{{H}_{2}}O\]

Correct Answer: D

Solution :

  Since, in above reaction, the same element, i.e. N is reduced as well as oxidised, so it is a disproportionation reaction.
