Medium MCQ +4 / -1 PYQ · JEE Mains 2025

The nature of oxide $\left(\mathrm{TeO}_2\right)$ and hydride $\left(\mathrm{TeH}_2\right)$ formed by Te , respectively are :

  1. A Reducing and basic
  2. B Reducing and acidic
  3. C Oxidising and acidic Correct answer
  4. D Oxidising and basic

Solution

<p>Tellurium dioxide ($\mathrm{TeO}_2$) acts as an oxidizing agent. This is because it can accept electrons and be reduced from its +4 oxidation state to a lower oxidation state.</p> <p>Tellurium hydride ($\mathrm{TeH}_2$) is considered acidic. This is due to its relatively low bond dissociation energy, which makes it prone to breaking, releasing protons (H$^+$).</p>
