Question

Like we did in class, draw the Newman projections for the aliphatic shown above about its C2-C3 bond in the eclipsed. staggered, and skewed conformations. Use the templates below. Label al gauche interactions and calculate a torsional strain for each conformation. Plot a graph of the torsional strain observed as the aliphatic rotates about the C2-C3 bond. Begin with the totally eclipsed conformer with a dihedral angle of zero. Place into the box the total torsional strain for each conformer. Use the therm data given below. As gauche methyl-bromine interaction is worth 0.3 kcal/ mole as shown above eclipsing methyl groups eclipsing methyl-hydrogen eclipsing hydrogen-hydrogen torsio 3.0 kcal 1.3 kcal 1.0 kcal stra eclipsing methyl bromine eclipsing bromine-hydrogen eclipsing hydrogen-hydrogen torsio 1.1 kcal 1.0 kcal 2-1 kcal stra 5.5 5.0 M0.0 120 360 240 300 60 180 1.1 BrH H3 1.3 totally ecliaped 5.4 Give abeled names to conformers A-- C-

Explanation / Answer

Structures with 60 and 300 degrees describe a torsion angle between 30
