Draw the molecules cis-[PtCl2(NH3)2] versus trans-[PtCl2(NH3)2].
a) If you assume the NH3 groups rotate freely and the out of plane hydrogens do not lower the symmetry, what is the point group symmetry?
b) If the NH3 groups do not rotate freely, what are the possible point groups?
I have the drawn molecules just unsure how to find the point groups.

A. Enantiomers: Certain substances have the unique property of rotating the plane of plane-polarized light. Such light rotation is detectable with the aid of a polarimeter. In order for a molecule to be optically active it must be chiral. Chiral objects lack a plane of symmetry and are non-superimposable on their mirror images. A sp?- hybridized carbon atom can fulfill these requirements if all four of its substituents are different. 1. Methane a) Prepare a methane molecule and then substitute...
