1 . Answer ALL parts a) — c).
a) Use the principles of Valence Shell Electron Pair Repulsion (VSEPR) to predict the structures of the following species.
XeF2; [XeF3]+; XeF4
b) Some of the halogens form oxo-acids in which their oxidation state is +7. Comment briefly on the observations that:
i) fluorine does not form a compound of this type;
ii) the compounds of iodine (H5IO6) and chlOrine (HCIO4) have different structures.
2 。Draw the structure of the following coordination compounds and determine the oxidation state, da nt electronic configuration, ( t2 gm eg” Or emt2" configuration and the spin only magnetic moment of the metal atom.
i) [CO(H2O )6]2+
ii) [Fe(ox)s]3-, ox = oxalate dianion, C2O42-
