Select the set of compounds with oxidation-reduction duality.a)Cl2, H3...
Oxidation-reduction duality refers to the ability of a compound to act as an oxidizing agent or a reducing agent depending on the reaction conditions. In other words, it can either gain or lose electrons in a redox reaction.
The set of compounds with oxidation-reduction duality is:
b) Cl2, H3PO3, C6H5CHO, H2O2
Explanation:
- Cl2 (chlorine) can act as both an oxidizing agent and a reducing agent, depending on the reaction conditions. For example, in the reaction with FeCl2, it acts as an oxidizing agent, whereas in the reaction with NaI, it acts as a reducing agent.
- H3PO3 (phosphorous acid) can also act as both an oxidizing agent and a reducing agent. For example, in the reaction with HCl, it acts as a reducing agent, whereas in the reaction with H2O2, it acts as an oxidizing agent.
- C6H5CHO (benzaldehyde) can undergo oxidation to form benzoic acid, which is a stronger acid and a better oxidizing agent. It can also undergo reduction to form benzyl alcohol, which is a weaker acid and a better reducing agent.
- H2O2 (hydrogen peroxide) is a strong oxidizing agent and can undergo reduction to form water. It can also act as a reducing agent in the presence of certain catalysts.
Therefore, option B is the correct answer as it contains a set of compounds that have oxidation-reduction duality.
