The nature of oxide (TeO2) and hydride (TeH2) formed by Te, respectively are:
Classification of Elements & Periodicity · Class 11 · JEE Main Previous Year Question
The nature of oxide () and hydride () formed by Te, respectively are:
- a✓
Oxidising and acidic
- b
Reducing and basic
- c
Reducing and acidic
- d
Oxidising and basic
Oxidising and acidic
🧠 TeO2 oxidises; TeH2 is acidic Tellurium in is in the state. It readily accepts electrons to reach a lower oxidation state — that is oxidising behaviour. For hydrides in Group 16, acid strength increases down the group as the bond weakens. So is more acidic than or .
🗺️ Nail each part : Te is ; it acts as an oxidising agent (gets reduced to Te or ). : Weak acid in Group 16 hydride series — the bond is long and weak, so the proton is released more easily than from . Acidic character confirmed.
