Question

In the preparation of compounds of Xe, Bartlett had taken \[\ce{O^{+}_2 Pt F^{-}_6}\] as a base compound. This is because ______.

Options

• both O₂ and Xe have same size.

• both O₂ and Xe have same electron gain enthalpy.

• both O₂ and Xe have almost same ionisation enthalpy.

• both Xe and O₂ are gases.

Answer 1

In the preparation of compounds of Xe, Bartlett had taken \[\ce{O^{+}_2 Pt F^{-}_6}\] as a base compound. This is because both O₂ and Xe have almost same ionisation enthalpy.

Explanation:

Bartlett noticed that Xenon's first ionisation potential is nearly identical to that of oxygen and used Born-Haber calculations to predict the presence of a stable compound:

\[\ce{Xe^{+} Pt F^{-}_{6}}\]
