Noble gases were considered inert before 1962. Prior to this, Bartlett and Lohmann had previously used the highly ionization energy of `O_(2)` is `1165 " kJ mol"^(-1)`, which is almost the same as the value of `IE_(1)` for Xe `(1170 " kJ mol"^(-1))` . Experiments showed that when deep red `PtE_(6)` vapours were mixed with an equal volume of Xe, the gases combined immediately at room temperature to produce a yellow solid. Soon after this, it was found that Xe and F react directly to give Xe-fluorides.
Choose the correct answer :
What was the yellow solid obtained by them ?
A. `[XeF_(2)]^(+) [PtF_(6)]^(-)`
B. `[XeF]^(+) [PtF_(6)]^(-)`
C. `Xe^(+) [PtF_(6)]^(-)`
D. `[PtF_(4)][XeF_(7)]`
