(a)
Interpretation:
The Dash-wedge structure for the given Newman projection is to be drawn.
Concept introduction:
A dash -wedge structure is a three-dimensional representation of a molecule drawn using different representations for bonds in the plane of paper, and those projecting toward and away from the viewer.
The bond which is in the plane of paper is represented by a straight line. The bond which points away from the viewer is represented by a dash line. The bond which points towards the viewer is represented by a wedge line.
(b)
Interpretation:
The Dash-wedge structure for the following Newman projection is to be drawn.

- 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?arrow_forwardPlease look at the picture as it is related on my question. When do we decide that it is CH3 or H3C that we put while we are drawing the Newman projection?arrow_forwardFill in the Newman projection for the following molecule from the angle shownarrow_forward
