1. Draw these straightforward Lewis structures for these compounds and ions. CO2 HCCH H20 NO2 NH3 NO3 NH4+ PCI: H2CO CC14 The shape of molecules is determined primarily by the number of groupings ("electron domains") around the central atom. For the structures above there, are: Two electron domains around the central atom in CO2, HCCH Three electron domains around the central atom in H2CO, NO3-, NO2 Four electron domains around the central atom in NH3, NH4+, H20, PC13, CC14 2....
