Draw the Lewis structure of the following compounds and identify the point group. Indicate the symmetry operations you performed in determining the point groups. a. 1,8-Dichloronaphthalene b. Eclipsed dibenzenechromium (Hint: The Cr atom is sandwiched between the two-benzene ring in eclipsed conformation.) c. Borazine (B3H6N3) (Hint: The structure looks like benzene, but instead of C, B and N are the atoms in alternating order.)
