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...

Draw trans-1-ethyl-3-methylcyclohexane in its lowest energy conformation. Choose a chair from the Templates toolbar at the bottom. Make sure it’s the appropriate chair, including any heteroatoms. Replace the appropriate hydrogens with the appropriate −CH3 or other groups. Important: Never delete the hydrogen atoms or bonds in the ring or directly attached to the ring. Also, do not try to move them by drag and drop. These actions will break the chair conformation structures. Just replace them! If you are told...

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)....

1.) Carefully draw two very neat cyclohexane chair molecules with the “headrest on the left”. Then draw two very neat cyclohexane molecules with the “headrest on the right”. Use a ruler or straightedge for the lines and try to make the C-C bonds about the same length. The axial and equatorial bonds do NOT need to be shown for this problem. 2.) Carefully draw another cyclohexane chair molecule with the “headrest on the left”. To this drawing, draw all of...
