本题目来源于试卷: Models of Bonding & Structure B.2 The Covalent Model，类别为 IB化学
[单选题]
Which terms best describe the electron domainelectron domain geometry of $BrCl_5$?
A. Square pyramidal
B. Trigonal bipyramidal
C. Pentagonal planar
D. Octahedral
参考答案: D
本题详细解析:
The Br atom in $BrCl_5$ has one non-bonding and five bonding electron pairs. The electron domain geometry for six electron pairs is octahedral. The bonding pairs form a square pyramidal geometry, but this is the molecular rather than the electron domain geometry.
This question is categorized as very hard, as the student must deduce the geometry without the aid of a Lewis structure and also differentiate between molecular and electron domain geometries.
