Question

In the preparation of compounds of Xe, Bartlett had taken O2+ Pt F6- as a base
compound. This is because
(i) both O2 and Xe have same size.
(ii) both O2 and Xe have same electron gain enthalpy.
(iii) both O2 and Xe have almost same ionisation enthalpy.
(iv) both Xe and O2 are gases.

Answer 1

because O2  and Xe both have same ionisation energy.

Answer 2

Due to same ionization enthalpy of oxygen and Xenon, Bartlett had taken $O_2^+PtF_6^-$ as a base compound during the preparation of Xenon.

Explanation:

• t is a matter of fact that the most stable series of elements in the periodic table are noble gases as they are less reactive.
• It is because they have stable electronic configuration due which its disintegration of stability is a tedious process.
• Xenon is one such element that belongs to the noble gas family.
• Neil Bartlett through his experimentation came up with a new compound called $O_2^+PtF_6^-$.
• His studied showed him that, in the obtained compound the first ionization of molecular oxygen value - 1175 kJ/mol was nearly similar to that of Xenon which is 1170 kJ/mol.
• Later he used $O_2^+PtF_6^-$ as base and produced successfully produced a compound called $Xe^+PtF_6^-$.
