Question

Energy Relative energy from text (see chapter 4 of Smith text) RECORD DATA for each conformer in this table: Dihedral angle Distance C1-C4 Relative energy calculated calculated (kcal/mol) or (KJ/mol) 2.907 A 10 5593 kJ moll 60 3.088A 17.7217 " 120 3.621A -4.6788 180 13.871A 721.2379 IMPORTANT NOTES: Calculate the relative energy (calculated) by taking the lowest energy and subtracting it from the other energies. If you do this calculation correctly, one of the conformers should have a "relative energy (calculated) of zero, and all others should have positive energies. Now, plot the relative energies (calculated) on the y-axis vs. dihedral angle (x-axis) for the four conformers. Plot a second line in a different color or pattern, showing the energy values from the text.
