Problem 6. (30 points) The molecule shown below is a common steroid. Redraw this steroid as a careful perspective drawing, using chair conformations for the cyclohexane rings and a reasonable conformation for the cyclopentyl group. The Bring should have the same conformation as the chair cyclohexane you drew in problem 1. You do not need to show all of the hydrogens on the rings; it is only necessary to show the substituents and hydrogens that I have shown explicitly. You...

please answer following question and expain why.
1. It is important to remember that the same grouping of orbitals will have different symmetry labels when you solve for their irreducible representations in different point groups. For each point group listed, (i) solve for the reducible representation (Tred) of two 1s orbitals that are symmetric about the z axis. (ii) List the Mulliken symbols of the two irreducible representations (Tirrep) that you can determine from your Fred. (ii) If there was...
