2. (15 points) Draw the molecule naphthalene. Use lines and arrows to show all the symmetry operations in this molecule. Do not use rectangles to show mirror planes unless it's a horizontal mirror plane, but you can always describe using a few words where a symmetry operation is located. What is the point group for naphthalene?
Identify all of the symmetry elements H20, NH3, CH4. For each molecule, list the symmetry operations which commute.

Assign a symmetry point group to the following compounds
CIFOS [CHOSe]- [Cl4l) Point group: Point group: Point group: narinde
Give the point group (pt. group) for the following, list all symmetry elements (other than E; if there are 2C3’s, for example, in a character table, just write C3), and circle either Y or N to note whether the molecule is chiral (Y) or not chiral (N), and polar (Y) or nonpolar (N). Assume that Me = CH3 groups (e.g., #2, 8, 9) rotate freely, so ignore their H’s.Ph = phenyl, C6H5 3) BBr3 pt. group = ____ symmetry elements:...
