Label a curve of potential energy vs. dihedral angle for the Newman conformations of 2,3-dimethylbutane. In each case, the C-2 to C-3 bond rotates in the clockwise direction. Step 1: Translate line-bond notation to the Newman projection. Step 2: Identify Newman projections for each rotation. HI H Step 3: Identify the relative stability of each Newman projection. Step 4: Construct the energy diagram. Step 3: Identify the relative stability of each Newman projection. a. The Newman projection is most stable. b. The gauche interactions, the more stable the Newman projection. Let's compare the staggered conformations. We've already determined that the 60° Newman projection has 3 gauche interactions. a. How many gauche interactions are in the Newman projection at 180°? b. How many gauche interactions are in the Newman projection at 300°? c. Which is the most stable staggered conformation?
