Question

Show two different eclipsed and two different staggered conformtations of the molecule 2-methylbutane using the partial structures below and drawing in methyl groups where appropriate. Underneath each calculate the total strain energy for each structure given the torsional energies: [eclipsing H to H = 1 kcal, H to CH3 = 1.5 kcal & CH3 to CH3 = 4 kcal, and gauche CH3 to CH3 = 0.9 kcal]. Then determine the barrier to rotation around the C2-C3 bond in the molecule.Show two different eclipsed and two different staggered conformations of the molecule 2-methylbutane using the partial structures below and drawing in methyl groups where appropriate.

    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.
