First stable compound of inert gas was prepered by

Options

A. Rayleigh and Ramsay
B. Bartlett
C. Frankland and Lockyer
D. Cavendish

Answer

**Step-by-Step Solution:**

1. **Identify the First Stable Compound of Inert Gas:**
The first stable compound of an inert gas is identified as xenon hexafluoroplatinate, represented as \( \text{Xe}^+ \text{PtF}_6^- \).

2. **Determine the Scientist Who Prepared It:**
The compound was prepared by scientist Neil Bartlett.

3. **Understand the Preparation Process:**
Neil Bartlett initially prepared a compound of oxygen, which was \( \text{O}_2^+ \text{PtF}_6^- \). He observed that the ionization enthalpy (IE) of \( \text{O}_2^+ \) was approximately equal to that of xenon (Xe).

4. **Hypothesis Formation:**
Based on the similarity in ionization enthalpy, Bartlett hypothesized that if a stable compound could be formed with oxygen, a similar compound could also be formed with xenon.

5. **Successful Synthesis:**
Following his hypothesis, Neil Bartlett successfully synthesized the first stable compound of xenon, \( \text{Xe}^+ \text{PtF}_6^- \).

6. **Conclusion:**
Therefore, the first stable compound of an inert gas was prepared by Neil Bartlett.

**Final Answer:**
The first stable compound of an inert gas was prepared by Neil Bartlett.
