3. (a) A bond-line (dash/wedge) structure for butane is shown below. Using the Newman projection templates provided, draw the overall lowest energy (most stable) and overall highest energy (least stable) conformation possible in Newman projection form sighting down the bond indicated. Provide a brie explanation to justify the conformer shown for cach case. (2pts each correct Newman, 2pts for valid explanation) sight down CG- bond Lowest Energy (most stable) Highest Energy (least stable) Explain: (b) For the bond-line structure below...
Draw the Newman projection in staggered conformation for isoleucine by viewing the molecule along the C?2??C?3 bond. The perspective formula of isoleucine, an amino acid, is provided below. Draw the Newman projection in staggered conformation for isoleucine by viewing the molecule along the C-2-C-3 bond. Edit the Newman projection on the canvas. Replace the appropriate hydrogens with the appropriate -CH_3 or other groups. If you need to start over, Undo or choose a Newman projection from the Templates toolbar (bottom)....
n. Draw three eclipsed Newman projections along the indicated bond. Use the attached template and finish the drawing by attaching the lines and substituents. least stable eclipsed most stable eclipsed Br Below, draw three staggered Newman projections of the same molecule along the same bond. Use the attached template and finish the drawing by attaching the lines and substituents. least stable staggered most stable staggered 4 5 6 Name the molecule: B. Draw the most stable conformer of meso-2,3-dichlorobutane
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...

Pleqsw help with this question 3. (a) Consider the bond-line (dash/wedge) structure shown below. Using the Newman projection templates provided to the right of this bond-line structure, draw the overall lowest energy (most stable) and overall highest energy (least stable) conformation possible in Newman projection form sighting down the C C, bond indicated. Provide a one sentence explanation to justify for the overall most stable conformation. (Ipts each correct Newman, 2pts for valid explanation) sight down Cy-- - bond .23...

EXTRA HOMEWORK Chapters 28/29-Sugars/Amino Acids (Will be collected on NOVEMBER 29, 2018- THURSDAY:*8:30AM 1. Below is the "staggered structure of D-glucose: D-glucose (A) Starting from the "staggered" conformation, draw D-glucose as a Fischer projection (you will have to draw the "eclipsed" conformation first). Go through all of the steps to show how you came up with the Fischer projection of D-glucose. Your eclipsed...
use a Newman projection of the C3-C4 bond of 223-trimethy1-4-phenylhexane to show the most stable conformation first. Rotate through all of the eclipsed and staggered conformations. Using the energy values provided in the tables below calculate the relative energies of the different conformations. Plot the changes in energy in the graph diagram providd. Hint: Draw a 2D structure first and "bold" the bond viewed in your Newman projection. vided. 2D Structure Approximate Eclipsing Energy Values (kcal/mole) H Me Et i-Pr...
