The nature of oxide (TeO2) and hydride (TeH2) formed by Te, respectively are: (1) Oxidising and basic (2) Reducing and acidic (3) Oxidising and acidic (4) Reducing and basic

1. Oxidising and basic
2. Reducing and acidic
3. Oxidising and acidic
4. Reducing and basic

Correct answer: Oxidising and acidic

Solution

TeO2 is a higher oxidation state oxide that typically acts as an oxidizing agent, while TeH2, being a hydride of a metalloid, tends to exhibit acidic properties due to its ability to donate protons in reactions.
