Question

Which of the following is NOT an example of redox reaction?

विकल्प

• \[\ce{HF + OH^- -> H2O + F^-}\]

• \[\ce{3H3AsO3 + BrO^-_3 -> Br^- + 3H3AsO4}\]

• \[\ce{I2 + 2S2O^{2-}_3 -> S4O^{2-}_6 + 2I^-}\]

• \[\ce{C + O2 -> CO2}\]

Answer 1

\[\ce{HF + OH^- -> H2O + F^-}\]

Explanation:

In the above process, no species oxidation number changes. As a result, this isn't a redox reaction in the traditional sense.
