Question:
Which of the following noble gases exhibits higher oxidation states ?
Which of the following noble gases exhibits higher oxidation states ?
Show Hint
Xenon has low ionisation enthalpy and can use its empty d orbitals.
Updated On: Oct 1, 2026
- Ne
- Ar
- Kr
- Xe
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Understanding the Concept:
Noble gases are chemically inert because of closed shells and high ionisation enthalpy. Xenon, the largest of the common ones, has the lowest ionisation enthalpy and vacant d orbitals.
Step 2: Reasoning:
Xenon forms compounds like \(\text{XeF}_2\) (+2), \(\text{XeF}_4\) (+4), \(\text{XeF}_6\) (+6) and \(\text{XeO}_3\) (+6). Krypton forms only \(\text{KrF}_2\) (+2). Neon and argon form no stable compounds.
Final Answer:
Xenon shows higher oxidation states, option (D). \[ \boxed{\text{Xe}} \]
