- need help. Out of the four isomers shown above (menthol, isomenthol, neomenthol, and neoisomenthol), which isomer do you predict is the most stable? It may help to draw out each isomer in its most stable chair conformer to determine which has the most equatorial groups.Create a conformational analysis using the molecule in the picture. Follow the instruction in the picture when you transform the molecule into its Newman projection. Which conformer is the most unstable? Explain.Consider the Newman projection below. a. Draw a full Lewis structure of this molecule with R1=Me,R2=Et , and R3=iPr . b. Given the sizes of these R groups (R3R2R1) , does the Newman projection above show thelowest potential energy conformation of this bond? If not, draw a Newman projectionshowing the lowest P.E. conformation (sighting down this same bond). c. To draw a Newman projection in the lowest P.E. conformation, the following rule of thumbusually applies: Place the largest group on the front carbon anti to the largest group on theback carbon. Is your answer to the previous question consistent with this rule of thumb?
- Consider the molecule 1-bromo-2-methylbutane. C3 and C4 should be drawn as Et as in theexample. This group is called an ethyl group and can be considered a sphere about twice the sizeof a methyl group. Draw the following Newman projections sighting down the C1C2 bond... a. The lowest potential energy conformation. b. The highest potential energy staggered conformation.Using your model of butane (CH3CH2CH2CH3) , complete the following graph of the anglebetween the two Me groups vs. potential energy. a. Label each Newman projection of butane on the graph with the words staggered, eclipsed, gauche, and anti, as appropriate. (Note that some structures will have more than one label.) b. Draw a wedge and dash bond representation of butane in its lowest P.E. conformation.Create a conformational analysis using the molecule in the picture. Follow the instruction in the picture when you transform the molecule into its Newman projection. Which conformer is the most stable? Explain.
- Which conformation shown below is the most stable conformation of 2-methylbutane?Consider 1,2-dimethylcyclohexane.Q: Which isomer, cis or trans, is more stable and why?translate the bond-line notation structure to the Newman projection by filling int the missing groups (A, B, C, D or E) on the lines in the Newman projection so they match the conformation given in the original structure. Circle if the conformation is a staggered or eclipsed.
