- Draw three-dimensional depictions of the following molecules.
For each molecule provide theoretical bond angles, shape, and
electron group geometry (ie octahedral, tetrahedral, bent, etc.).
For each molecule, provide all possible structural and
geometric isomers. If the molecule/ion possesses resonance
structures, draw all relevant structures? What is the point group
of each structure? If the compound is chiral, draw its enantiomer.
- NiCl2(NH3)2 (tetrahedral)
- PCl2F3
- NO3-

Draw Lewis structures for the following molecule and ions. For each of these structures
a) Draw Lewis structures for the following molecule and ions. For each of these structures, the octet rule must be satisfied, and all lone pairs must be shown. Name the molecular geometry for each and also specify if they are polar. If a molecule has more than one resonance structure, draw just the best one. Show formal charges only if they are not zero. b) Which compound(s) above will not have ideal bond angles about the central atom? Circle your choice(s). CNF ...
