The anti conformation of 1, 2-dichloroethane, Cl-CH_2-CH_2- Cl, is 4.81 kJ mol^-1 (1.15 kcal mol^-1) more stable than the gauche conformation. The two energy barriers (measured relative to the energy of the gauche conformation) for carbon-carbon bond rotation are 21.5 kJ mol^-1 (5.15 kcal mol^-1) and 38.9 kJ mol^-1(9.3 kcal mol^-1). Sketch a graph of potential energy versus dihedral angle about the carbon-carbon bond. Show the energy differences on your graph and label each minimum and maximum with the 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. H,H eclipsing interaction = 1 kcal/mol H,CH3 eclipsing interaction =...

9.78 The two lowest energy conformations of pentane are the anti-anti and the anti-gauche forms, in terms of arrangements around the two central C─C bonds. A recent study analyzed the conformations of 3-heptyne as an “elongated” analogue of pentane, where a carbon-carbon triple bond is “inserted” between C2 and C3 of pentane.[15] Interestingly, the researchers found that in each of the two most stable conformations of 3-heptyne, C1 and C6 are nearly eclipsed (looking down the alkyne group). In one...
