8. Draw 2-methylpentane. a) Draw Newman projections for the six energy maxima and minima for rotation around the C2-C3 bond. b) Calculate the energy at each conformation. (Assume the same energies for -Et as you would for Me. c) Use these values to make a graph of potential energy versus dihedral angle. d) Label the most stable conformation. e) Label the least stable conformation? f) What is the barrier to rotation around the C2C3 bond? 8.
