1.Draw a Lewis structure for each of them. Remember that some molecules violate the Octet Rule in different ways. Some of these use multiple bonds and some don't. You need to figure out which do. Use the rules we had in class for writing Lewis structures and compare with these with the molecules we did write Lewis structures for. None of these have resonance structures.
SF6 CH4 I3- N2 XeF4 NH3 OH- CO C2H4 (in this molecule there is no one central atom, the two carbons are bonded together and in addition each carbon bonds with two hydrogen atoms)
2.Draw a Lewis structure for each of the following. For two of these molecules there are resonance structures. See if you can identify which two they are and draw the resonance structures.
NF3 NO3- O2 SO2 NO+ PCl3 F2 HCl OF2 IF
