On each structure show how you determined where each group goes.How to draw a Newman Projection 1. Find the side view you are going to be using ... you can draw the Newman projection of the front carbon first. If a side group is on a wedge, that means it is coming out of the paper (towards you), so that can be written as a line toward the right. Reversely, a side group on a dash means it is going into the ... The sawhorse and Newman projections are also very helpful when working for larger molecules.

While organic chemists prefer to use the dashed/solid wedge convention to show stereochemistry, biochemists often use drawings called Fischer projections and Haworth projections to discuss and compare the structure of sugar molecules. Fisher projections show sugars in their open chain form. In a Fischer projection, the carbon atoms of a sugar ...

In order to draw a Newman projection from a wedge-dash diagram, it is useful to imagine putting your "eye" in line with the central bond in order to look along it.

Draw the Newman.Draw the most energetic Newman Projection of CH 3 CH (C 6 H 5 )CH 3. Hint:Not all Newman Projections can form an anti, gauche and eclipsed conformation. If you have no clear large group on one side of the projection, you’ll just be stuck with projections called staggered (not overlapping) and eclipsed (overlapping).This hydrogen and this hydrogen is this hydrogen and this hydrogen. And when you look at it this way, now you say, oh, now I can see how I would draw a Newman Projection. I put this in the front, that in the back. I treat this whole part of the molecule as just a group, if you will. It is a group. So lets do the Newman Projection here.Step 1. Find the longest continuous chain of carbon atoms. There is one C atom at the centre of the circle and a second one hidden at the back of the circle. A methyl group off the back adds a third C atom. On the front carbon, the ethyl group has the longest chain, for another two C atoms. We draw a 5-carbon chain.In a line drawing, this butterfly shape is usually shown from the side, with the near edges drawn using darker lines. ...

Fill in the remaining column in the table above. Fill in the graph below showing the energy of the conformations. Why is there such a BIG energy difference between the conformation with a dihedral angle of 0° and 120°? In a Fischer projection drawing, the four bonds to a chiral carbon make a cross with the carbon atom at the intersection of the horizontal and vertical lines. The two horizontal bonds are directed toward the viewer (forward of the stereogenic carbon). The two vertical bonds are directed behind the central carbon (away from the viewer). wired202808 said: I've never seen a problem where you had to assign an R or S from a newman projection. and i wouldnt bother trying to solve it that way because you might confuse yourself and mess up. i like seeing things in fischer projections because that's the fastest and least erroneous method of assigning R/S.

In order to draw Fischer Projections, we start out by translating the 3D conformation of the molecule into wedges and dashes.

Hint:Not all Newman Projections can form an anti, gauche and eclipsed conformation. If you have no clear large group on one side of the projection, you’ll just be stuck with projections called staggered (not overlapping) and eclipsed (overlapping).For a sugar drawn in a Fischer projection with the most oxidized group at the top (i.e. a carboxylic acid or aldehyde), a chiral center with OH on the right will be R, and a chiral center with OH on the left will be S. This makes assigning R and S to sugars in the Fischer projection a very quick process. marni hughs Which Newman projection correctly represents the wedge and dash drawing exactly as shown without rotation sighting down the C1 to C2 bond?
