Molecules of the most electronegative elements, compounds having an element in the highest oxidation state, and oxides of metals and nonmetals are examples of oxidizing agents. But sodium hydride is a metallic hydride, so it is not an oxidizing agent.

Which of the following is not an oxidising agent?a)magnesium oxideb)ca...
Explanation:
What is an oxidising agent?
An oxidising agent is a substance that can accept electrons from another substance during a chemical reaction. It causes the other substance to be oxidized.
Identifying the oxidising agent:
- Magnesium oxide: Magnesium oxide is formed by the oxidation of magnesium. It is not an oxidising agent itself but rather a product of oxidation.
- Carbon dioxide: Carbon dioxide is a non-reactive gas and does not have the ability to accept electrons from other substances. Therefore, it is not an oxidising agent.
- Ozone: Ozone is a powerful oxidising agent as it readily accepts electrons from other substances, causing them to be oxidized.
- Sodium hydride: Sodium hydride is a reducing agent, not an oxidising agent. It donates electrons during chemical reactions.
Conclusion:
Among the options given, sodium hydride (option D) is not an oxidising agent. It acts as a reducing agent by donating electrons rather than accepting them.
