Complete the following for the molecules or ions below (see parts a, b, c below): SiH4 NH3 H2O CO2 SO2 CH2O CH4 BH3 PF5 XeF4 ClF3 XeF2 SF4 SF6 NO2- CO32- CN- I3- SF5- NH4+ a. Draw the Lewis Structure (be prepared to justify your Lewis structure and why you believe it is the correct structure, when you input your exam answers in the 40-minute exam answer submission file on blackboard. For instance, justification can be provided by showing/explaining formal charge calculations, as well as obeying octet rule and exceptions to octet rule, etc…) b. Identify the molecular geometry (shape) c. Identify the hybridization of the central atom d. State the bond angle for the following molecules or ions: H2O CO2 SO2 NH3 NH4 + CH4 BH3 e. Explain the difference between a sigma and pi bond. f. Identify the number of π bonds and σ bonds in the caffeine (C8H10N4O2) molecule below.
