Neil Bartlett made efforts to prepare compound of a inert gas [P] with a metal fluoride [Q] and he

Options:(select one or more)

Answer:
A, D
Solution:

[P]⁺[Q]⁻ = [Xe]⁺[PtF₆]⁻. Xe⁺ has 53 electrons; its penultimate shell (n = 4) holds 18 electrons (A ✓).

PtF₆ oxidises Xe, but in [PtF₆]⁻ platinum is Pt(V), d⁵, not d⁶ (B ✗).

|ΔH_EGE| of Xe⁺ = ionisation energy of Xe (≈1170 kJ/mol), higher than Cl (C ✗).

Fluorine stays −1 (D ✓).

Correct: (A), (D).
