1. For each of the following six molecules or ions, draw the structure and add the key symmetry elements on the drawing that are used to identify the point group. [Fe04]?; xenon difluoride; nitrobenzene (2 conformers); formaldehyde (methanal); fac-[W(1)3(CO):] Then for each provide the point group and state whether or not the molecule is chiral and whether it has a permanent dipole moment
