How to draw newman projections from wedge dash.
The gauche interaction occurs in butane occurs when the two methyl groups have dihedral angles of 60° and 300° and arises because the methyl groups are still quite close together (about 3.1 Å, compare to 2.9 Å) for the syn – conformation. The strain energy of the gauche interaction is about 0.9 kcal/mol.
To show stereochemistry, we must use wedge-dash formulas. These formulas give the stereochemical information. But it is easiest to compare structures using Fischer projections, because they are always written in the same way. If we make the wedge-dash formula vertical with C-1 at the top, it becomes structure B above.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.In order to better visualize these different conformations, it is convenient to use a drawing convention called the Newman projection.

A planar structure for cyclohexane is clearly improbable. The bond angles would necessarily be 120º, 10.5º larger than the ideal tetrahedral angle. Also, every carbon-hydrogen bond in such a structure would be eclipsed. The resulting angle and eclipsing strains would severely destabilize this structure.

There is an entirely different way to draw stereocenters (instead of using regular bond-line drawings with dashes and wedges).The sawhorse representation combines the wedge and dash model and the Newman projections. It extends out the bond on the Newman projection, like on a wedge and dash model, but keeps the bonds ...Thus, the correct Newman projection will be determined by which atoms in the wedge-and-dash drawing are connected by the bond being viewed. Explanation: The wedge-and-dash representation of molecular structures signifies the three dimensional structure of the molecules.

(Hint: first decide whether the confirmation is staggered or eclipsed) Select the correct Newman projection below, and drag the three groups (X, Y, and Z) to their correct locations. There's just one step to solve this.The first things to note when drawing Fischer projections are the general rules for drawing them. The first general rule concerns the choices of 'top' and 'bottom' while the second concerns how each cross is interpreted.

Convert the bond-line structure to a wedge-dash structure at C-2 and C-3. Step 2. Convert the wedge-dash structure to a sawhorse projection. We must look at the molecule along the C2-C3 bond (from the lower left). The three bonds nearest us form an inverted "Y". We draw a sawhorse template with the C2-C3 bond going from lower left …So as a Newman Projection the front's going to look the same. You have a hydrogen there, you have this hydrogen, you have that hydrogen, and then you have that blue, or I guess that purple hydrogen, down here. So that's the front of it. But the back, they're right behind it's. So let me draw the back carbon. If drawing a Newman projection does not look like an option you’d take, remember that there is also the swap method for determining the R and S configuration. So, when the lowest priority is neither wedge nor a dash, there is this simple yet such a useful trick making life a lot easier. And that is the swap method. The aldehyde group representing carbon 1 goes at the top. Step 2: Draw horizontal lines to make crosses at C-2, C-3, C-4, and C-5. Step 3: Put the OH groups on the exact side of the cross. Step 4: Remove C-2, C-3, C-4, and C-5, and the Fischer projection is obtained.
