JEE Advanced Chemistry question

The [XeF]+ ions are attached to anion [AsF6]⁻

(A)With a linear F-bridgeCorrect
(B)With an angular F-bridge
(C)With H-bond
(D)With tetrahdral F-bridge

Answer: (A)

Solution

In the ionic solid [XeF]⁺[AsF6]⁻, the cation and anion are not fully "free" ions but are held together through a fluorine bridge: one fluorine of the octahedral AsF6⁻ anion interacts with the electrophilic Xe centre of [XeF]⁺, and this Xe···F···As
