B) trigonal planar / bent (120º)

Draw the Lewis structure of ozone (O₃) and then determine its electron domain and molecular geometries. A) planar / trigonal planar B) trigonal planar / bent (120º) C) trigonal / trigonal planar D) planar / trigonal E) pyramidal / pyramidal

B) trigonal pyramidal (pyramidal) *Trigonal pyramidal (pyramidal). Ammonia has three groups and one set of lone pairs bound to a central atom, which affords a trigonal pyramidal, or pyramidal, molecular geometry based on Valence Shell Electron Pair Repulsion Theory
