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)....

Procedure B. 1. Build two models of 1, 2-dimethyleyclopentane. The two methy can be on the same face or opposite faces of the ring. No matter how t molecule is twisted, they cannot be superimposed on each other. These compounds are stereoisomers of each other. 2. When two groups are present, the prefix cis (same face) or trans (opposite face) can be used in IUPAC nomenclature to specify which stereoisomer is being considered. For drawings, a solid wedged line in...
