Question

The first compound of noble gas prepared by Bartlett was

• A. XeOF\(_4\)
• B. Xe\(^+\) [PtF\(_6\)]\(^-\)
• C. XeF\(_4\)
• D. XeF\(_6\)

Hint:

This discovery opened up the field of noble gas chemistry. Since then, many compounds of xenon and krypton have been synthesized.

Answer 1

The Correct Option is B

Step 1: Basic Principle
Neil Bartlett discovered the first noble gas compound in 1962.
Step 2: Solution Procedure:
Bartlett observed that PtF\(_6\) (a strong oxidizing agent) could oxidize O\(_2\) to O\(_2^+\)[PtF\(_6\)]\(^-\). Since the ionization energy of Xe (1170 kJ/mol) is similar to that of O\(_2\) (1175 kJ/mol), he reasoned that PtF\(_6\) could also oxidize Xe. He reacted Xe with PtF\(_6\) and obtained the first noble gas compound, xenon hexafluoroplatinate, Xe\(^+\)[PtF\(_6\)]\(^-\).
Step 3: Required Answer:
The first noble gas compound prepared was Xe\(^+\)[PtF\(_6\)]\(^-\), option (B).
