Question

The formation of O2+ [PtF6]- is the basis for the formation of xenon fluorides. This is because :

Options

A.O2 and Xe have comparable sizes.
B.both O2 and Xe are gases.
C.O2 and Xe have comparable ionisation energies.
D.O2 and Xe have comparable electronegativities.

Solution

In March 1962, Neil Bartlett, then at the University of British Columbia, observed the reaction of a noble gas. First , he prepared a red compound which is formulated as O2+ [PtF6]- and it is already know that the first ionisation enthalpy of molecular oxygen (1175 kJ mol –1) is almost similar with that xenon (1170 kJ mol -1). Then he made efforts to prepare same type of compound by mixing Pt F6 and Xenon Xe+ [PtF6]- . After this discovery, a number of xenon compounds mainly with most electronegative elements like fluorine and oxygen, have been synthesised.
