C) tetrahedral / tetrahedral

Draw the Lewis structure of CBr₄ and then determine its electron domain and molecular geometries. A) trigonal / planar B) linear / trigonal pyramidal C) tetrahedral / tetrahedral D) planar / trigonal E) planar / tetrahedral

Lewis structure of Cl₂.

Draw the Lewis structure of Cl₂.

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

What is the correct molecular geometry of NH₃ according to Valence Shell Electron Pair Repulsion Theory? A) trigonal planar B) trigonal pyramidal (pyramidal) C) bent D) tetrahedral
