Draw a chair conformer and the ring-flipped conformed and determine which conformer for each pair you drew in part(a) is more stable.
(i) 1-tert-butyl-1-methylcyclohexane
(ii) cis-1-tert-butyl-3-methylcyclohexane
a. Using the wedge-and-dash notation, draw the nine stereoisomers of 1,2,3,4,5,6-hexachlorocyclohexane. b. From the nine stereoisomers, identify one pair of enantiomers. c. Draw the most stable conformer of the most stable stereoisomer.
Consider pentane, C5H12. Looking through the internal C3-C4single bond, draw thesix Newman projections (where the angle between two bonds as you look through the C3and C4bond is either 0°or 60°of the different conformations. Label the conformers/rotamers using I, II, etc.
a.Which conformer is the most stable? the least stable?
b.Which rotamer is the anticonformer? the gaucheconformer?
