Homework #6: Molecular geometry
Directions:
Part 1: For the molecules listed below show the four steps necessary to determine shape (work can be done on separate piece of
paper and stapled to summary chart)
Part 2. Create and fill in a summary chart similar to this for the molecules in part 1* :
molecule
Lewis
structure
Electron
#bonded # lone
pair
pairs on pairs

Molecular drawing Bond
angles
SO2, CF4, NI3, F2S, CCl2O, CO32-, NO21-, I3-, H2O, NH3, CH4, SiO2, SiH2O, HCN, SCN, XeF2, BH3
*for those molecule that exceed octet, only Lewis structure is necessary to know
3. Identify those molecules that can have resonance structures and show them.
