For each of the following, write the Lewis structure(s), predict the molecular structure (including bond angles), and give the expected hybridization of the central atom. a. \(\mathrm{KrF}_{2}\) b. \(\mathrm{KrF}_{4}\) c. \(\mathrm{XeO}_{2} \mathrm{~F}_{2}\) d. \(\mathrm{XeO}_{2} \mathrm{~F}_{4}\)

a. \(\mathrm{KrF}_{2}\): Lewis structure: Kr[F]-2; Molecular structure: linear; Bond angle: 180°; Hybridization of Kr: \(\mathrm{sp}^3\) b. \(\mathrm{KrF}_{4}\): Lewis structure: \({{Kr\!\left(\underset{\bullet}{\phantom{F}}_{}^{F}\right)}}\!\!{}^{-}_{F}^{-}_{F}\); Molecular structure: square planar; Bond angle: 90°; Hybridization of Kr: \(\mathrm{sp}^3\mathrm{d}\) c. \(\mathrm{XeO}_{2}\mathrm{F}_{2}\): Lewis structure: \({{Xe\underset{\bullet}{\phantom{O}}_{}^{O}\Big(\!\!{}^{F}\backprime\:\!}_{F}\Big)}\); Molecular structure: square planar; Bond angle: 90°; Hybridization of Xe: \(\mathrm{sp}^3\) d. \(\mathrm{XeO}_{2}\mathrm{F}_{4}\): Lewis structure: \({{Xe\underset{\bullet}{\phantom{O}}_{}^{O}\Big(\!\!{}^{F}\backprime\:\!}_{F}\Big)}\!\left\{\!\!\!\!\!\!{}_{F}^{F}\right\}\); Molecular structure: octahedral; Bond angle: 90°; Hybridization of Xe: \(\mathrm{sp}^3\mathrm{d}^2\)
