Question

what is the electron - domain geometry of the structure below? octahedral trigonal planar tetrahedral trigonal bipyramidal linear

Explanation:

Electron - domain geometry is determined by the number of electron domains (bonding and non - bonding) around the central atom. An octahedral electron - domain geometry occurs when there are 6 electron domains. In the given structure, we can assume (based on the typical representation of such geometries) that there are 6 electron domains around the central atom (the purple sphere). Trigonal planar has 3 electron domains, tetrahedral has 4, trigonal bipyramidal has 5, and linear has 2.

Answer:

Octahedral
