- A 1, 2-cis disubstituted cyclohexane, such as cis-1, 2-dichlorocyclohexane, must have one group axial and one group equatorial. Explain.Measure the C-C-C and C-C-H bond angles in the energy-minimized models of cis and trans isomers of cyclooctene. Compare these values with those predicted by VSEPR. In which isomer are deviations from VSEPR predictions greater?Why are these two conformational isomers? I was under the impression that in molecules with only sigma bonds, the bonds can rotate freely, and so the placement of the chlorines wouldn't matter?
- Determine the structure of the unknown compound with the molecular formula C13H1602How do we distinguish between constitutional, configurational, conformational, and enantiomers?Perform a conformational analysis of 2-methylbutane, (CH3)2CHCH2CH3, looking down the C2-C3 bond. Pay attention to the relative energies of the various conformations, but do not concern yourself with the actual energy values.
- 5. Explain with the aid of conformational structures why trans-1,2-dimethylcyclohexane is more stable than cis-1,2-dimethylcyclohexane, whereas the reverse order of stability is observed for the 1,3-isomer.How would you best describe the C-C bonds lengths in benzene relative to cyclohexane? Hypothesize why these results are observed.Compare the relative conformational energydiagrams of ethane and propane.
