Question

In the preparation of compounds of $Xe$, Bartlett had taken $O^+_2\, PtF_6^-$ as a base compound. This is because

• A. both $O_2$ and $Xe$ have same size
• B. both $O_2$ and $Xe$ have same electron gain enthalpy
• C. both $O_2$ and $Xe$ have almost same ionisation enthalpy
• D. both $Xe$ and $O_2$ are gases

Answer 1

Answer: (C)

First ionisation enthalpy of $O_2 (1175\, kj\, mol^{-1})$ is almost identical with that of xenon $(1170\, kj \,mol^{-1})$.
