Question 6 (2 points) Consider the rotation around the C2-C3 bond of 2-methylbutane. Using the values listed below, calculate the energy corresponding to (eclipsed or staggered) conformations at each 60° rotation. Define the dihedral angle (6) as the angle between the H on C2 and the methyl group on C3. Begin at the O° dihedral angle (placing C2 in front and C3 in back) and turn clockwise the front carbon. H,H eclipsing interaction = 1 kcal/mol H,CH3 eclipsing interaction =...
