3.A. Use our "curves" notation to indicate the gauche interactions on the Newman Projections below, and circle the eclipsing interactions. 3.B. Catalog the steric interactions below, using the designation "G" for gauche and "E" for eclipsing. 3.C. Assuming that the CH3 group is sterically larger than the Cl group, rank the rotational states from lowest energy to highest energy. \begin{tabular}{clllll} Lowest Energy & & & & \multicolumn{2}{c}{ Highest Energy } \\ \cline { 3 - 6 } & 0 & 0 & 0 & 0 & 0 \\ 0 & 60 & 60 & 60 & 60 & 60 \\ 60 & 120 & 120 & 120 & 120 & 120 \\ 120 & 180 & 180 & 180 & 180 & 180 \\ 180 & 240 & 240 & 240 & 240 & 240 \\ 240 & 300 & 300 & 300 & 300 & 300 \\ 300 & & \end{tabular}
