Which of the following species exhibits a trigonal bipyramidal arrangement?
- XeO3F2
- XeO3F2
- FXeOSO2F
- [XeF8]2−
Correct answer: XeO3F2
Solution
In XeO3F2 the Xe atom forms three Xe=O and two Xe-F bonds with no lone pair, giving five electron domains and a trigonal bipyramidal shape. [XeF8]2- is square antiprismatic, not TBP.
