Question

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

Explanation:

Electron - domain geometry is determined by the number of electron domains (bonding and non - bonding) around the central atom. In this structure, there are 3 electron domains (2 bonding and 1 non - bonding). Trigonal planar geometry occurs when there are 3 electron domains around the central atom.

Answer:

Trigonal planar
