Please answer in detail 5. Draw the Newman projections for the anti conformation and two types of eclipsed conformations of 1,2-diiodoethane. Of the two eclipsed conformations, which is of higher energy, and why?
4 4. (a) Draw the structure of the two chair forms of methylcyclohexane. Draw in all bonds (even the C-H bonds). Be sure the axial and equatorial bonds are shown correctly. On the appropriate structure, indicate the 1,3-diaxial interactions involving the methyl group. (b) Which is more stable, trans-1,3-dimethylcyclohexane or cis-1,3-dimethylcyclohexane? Why? 5. Draw the Newman projections for the anti conformation and two types of eclipsed conformations of 1,2-diiodoethane. Of the two eclipsed conformations, which is of higher energy, and...
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...
Understanding Conformation Analysis Draw two Newman Projections for a n-pentane that depict and anti and gauche conformation looking down the c2-c3 bond. Which conformation is the most stable and why?
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...
