CHM 094 Practice #5 Name ____________________1. Name the following compounds:NH3N2Br4NO2COCO2NON2OBrClCH42. Write the chemical formulas for the following compounds:Dinitrogen pentoxideNitrogen trifluorideAmmoniaCarbon monoxideSulfur trioxideSulfur dichlorideSilicon tetrachlorideMethaneCarbon tetrafluorideDihydrogen monoxideWater3. Draw valid Lewis structures, and determine the molecular geometries of the following molecules and ions using the VSEPR theory. For cations subtract one electron from the total of valenceelectrons, for anions add one electron to the total of valence electrons. You will need an extra sheetof paper to complete this assignment (please staple it to this one).SiH4; PCl3; CO2; CCl4; H2O; NF3; O3; OF2; NH4 +; NH2?; AlH4?; H3O+; BF4?; BrF2 +; CI4.Very important: in BF4? B obeys the octet rule;in BrF2 + Br is the central atom and it is allowed to have more than 1 bond.
