Problem #1: Molecular Geometries (40 points) Choose ONE of the following molecules or polyatomic ions: COC12, O3, CO3, NO2, NO3, PO4³-, SO4² or Xeo,* For the molecule / polyatomic ion, provide the following: a) Total number of valence electrons [2 points] b) Lewis structures for all possible resonance structures [6 points] c) Draw the most stable structure. Make sure this answer is clearly stated separately away from your list of resonance structures, even if you decide it is one of the resonance structures. (hint: sometimes the most stable structure is one of the resonance structures, while other times it is a HYBRID of some/all of the resonance structures) [6 points] d) Formal charges on all atoms of each resonance structure AND the most stable structure, supported with calculations. [8 points] Then, based on the most stable structure [2 points each]: e) 3D Drawing, using wedges and dashes if necessary. f) Hybridization of the central atom (from Valence Bond Theory) g) # electron domains, # atoms bonded to the central atom, # lone pairs on the central atom h) Electronic Geometry (aka Parent Geometry) i) Molecular Geometry j) All bond angles k) Bond polarities 1) Overall molecular polarity m) In a pure sample, the types of intermolecular interactions that occur (London Dispersion, Dipole-Dipole, and/or Hydrogen Bonding)
