5. Construct a model of 1,2-difluoroethane. Draw the Newman projections for the staggered and eclipsed conformations of 1,2-difluoroethane. Are these molecules isomers or conformers? If they are isomers to what specific category do they belong? 6. The structure of cyclohexane (C6H12) is based on a six membered ring of carbon atoms. Construct a model of cyclohexane. Cyclohexane can exist in two conformations; the boat or chair conformation (shown below). What are the C-C-C, C-C-H, and H-C-H bond angles at each...
Using Newman projections, draw all the staggered and eclipsed conformations that result from rotationaround the indicated bond in 2-methylbutane(shown below) and place these on a graph of energy versus dihedralangle for a 360° rotation about this bond. To orient your graph, one structure has been filled in for you. Please start your conformational analysis and energy curve from this structure.
using the c3-c4 axis, draw newman projections for an eclipsed and a staggered conformation of 2.5 dimethylhexane. Draw the most stable conformation for the molecule as well.
