How to draw newman projections from wedge dash.
In Wedge-Dash notation the bond which protrudes out of the plane of paper towards the viewer is denoted by a solid wedge while that project far away from the viewer or into the plane of the paper is denoted by a dashed wedge and therefore the bond within the plane of the paper is represented by a line.
Using dashes and wedges, draw first the R, R and then the R, S diastereomer of 2, 3-dibromopentane. Under each of these dash and wedge structure. draw Newman projections ( C 2 ? C 3 bond) of that str; Draw a Newman projection of the following compound as viewed down the indicated bond in the conformation shown.Using dashes and wedges, draw first the R, R and then the R, S diastereomer of 2, 3-dibromopentane. Under each of these dash and wedge structure. draw Newman projections ( C 2 ? C 3 bond) of that str; 3. Write Newman projections for all three staggered conformations of 2,2-dimethylpentane looking down the C-l C-2 bond.$\begingroup$ A side note: For the question in title, you could just move on with the Newman projections to determine the relative stabilities of various conformers. Large groups which are anti to each other have the least energy possible, and hence are more stable. I don't see why you want to convert the Newman structures to 3d bond line structures for the question and I consider it to be ...This problem has been solved! You'll get a detailed solution from a subject matter expert that helps you learn core concepts. Question: Translate the given theoretical conformer from the wedge-and-dash drawing into its Newman projection. Make a model to match and confirm the placement of the substituents.Drawing a Newman Projection. 1. Determine which two carbon atoms are being studied. A Newman Projection focuses on one specific bond of the molecule, and note which atoms are attached to these carbon atoms. Add an eye with an arrow looking down the carbon-carbon bond being studied. Example: 2-3 means looking down the carbon 2 and carbon 3 bond.
If we start at carbon one, we start up axial, so let's go ahead and put in the axial hydrogens on our Cyclohexane, on our chair conformation. So here is carbon one. We're gonna draw a line straight up and put in a hydrogen. We go to carbon two. We draw a line straight down and put in a hydrogen.Choose one side to be the wedges, the other side to be the dashes. In the example below, we made the wedges on the left and the dashes on the right. Now "turn" the molecule 90° so the wedges are in front and the dashes are in the back. The "12:00 and/or "6:00" of the Newman become the thin lines of the wedge-dash structure.
Because that puts the hydrogen as a dash, so R/S is easy to assign. With two wedges, the structure is (2R, 3R). So the 2R position is fine, and we just switch the wedge at C-3 to a dash, and the structure is correct (2R,3S). To draw the Fischer projection, we do something similar- arbitaritly draw a structure, check R/S, and then adjust as ...video on newman projections. drawing Newman projection video.

Put the #"CH(CH"_3)_2# group on the bottom. The two #"H"# atoms go on the other bonds. The groups on #"C-4"# go on the back carbon.Ans. Here's how you can convert a Wedge-Dash projection to a Newman projection: 1. Identify the central carbon in the Wedge-Dash projection. 2.

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).Hint: Using wedge and dash notation, solid lines (sticks) represent chemical bonds in the plane of the surface. Black wedges represent chemical bonds coming toward you, while dashed lines are for bonds that extend back behind the surface. .We must view a wedge-dash formula from the correct angle to convert it to a Fischer projection.The Newman projection is obtained upon a 90° degree rotation of the dash-wedge structure.

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.
