How are the structures of xenon fluorides determined, and what are the shapes of XeF 2 and XeF 4 ?

Options

ABy X-ray crystallography; XeF 2 is linear, XeF 4 is square planar
BBy VSEPR theory; XeF 2 is square planar, XeF 4 is tetrahedral
CBy nuclear magnetic resonance (NMR); XeF 2 is tetrahedral, XeF 4 is square planar
DBy infrared spectroscopy; XeF 2 is tetrahedral, XeF 4 is linear

Correct answer

A. By X-ray crystallography; XeF 2 is linear, XeF 4 is square planar

Step-by-step solution

The structures of xenon fluorides are determined by X-ray crystallography, and the shapes are as follows: XeF 2 is linear, and XeF 4 is square planar.**
