Question

The formation of O2+ [PtF6]– is the basis for the formation of first xenon compound. This is because
(a) O2 and Xe have different sizes.
(b) both O2 and Xe are gases.
(c) O2 and Xe have comparable electro-negativities.
(d) O2 and Xe have comparable ionisation enthalpies.

Answer 1

Answer:

☑️☑️(b) Both O2 and Xe are gases☑️☑️

Answer 2

XENON FLUORIDES

The formation of O2+[PtF6] is the basis for the formation of first xenon compound because (d) O2 and Xe have comparable ionization enthalpies.

EXPLANATION :

* Xenon's initial ionization energy (1170 KJ mol-1) is quite similar to that of dioxygen (1180 KJ mol-1).

* Xenon and dioxygen have almost equal molecular diameters. Based on the aforesaid similarities, Barlett (who synthesized the O2+PtF6- molecule) proposed that since oxygen reacts with PtF6, xenon should react with PtF6 as well.

* Moreover, it wont be wrong to say that O2 and Xe have comparable sizes.
