Identify all of the symmetry elements H20, NH3, CH4. For each molecule, list the symmetry operations which commute.
As this is a question from group theory . so i am providing you the written solution .
sif
you have further confusion , feel free to ask me in the comment
section. thanks . please rate positive if you are satisfied with my
efforts.

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?
Find and list all symmetry elements present in the molecules
below, and assign a point group to each. Indicate the principal
axis (z axis) on each drawing. Note: Different resonance structures
involving p-bonds do not destroy symmetry elements. You can assume
the highest level of symmetry depicted in the drawings.

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:...
