Which of the following statements is correct?

The processes $\mathrm{Xe}\left(\mathrm{g}\right)\to {\mathrm{Xe}}^{+}\left(\mathrm{g}\right)+{\mathrm{e}}^{-}$ and ${\mathrm{O}}_2\left(\mathrm{g}\right)\to {\mathrm{O}}_2^{+}\left(\mathrm{g}\right)+{\mathrm{e}}^{-}$ involve more or less identical ionization energy

${\mathrm{XeF}}_2$ possesses an angular structure

${\mathrm{XeF}}_2\mathrm{F}$ possesses a trigonal bipyramidal structure with xenon and fluorine atoms occuping linear position and the three lone pairs occupying equatorial position

${\mathrm{XeF}}_4$ is regarded as pseudo-octahedral with fluorines occupying the corners of a square plane
