Civil engineering is a field that requires precision, collaboration, and efficient project management. Traditionally, civil engineers have relied on in-person meetings, physical dr...Draw the resulting reduction product of attaching a hydride on that face of the molecule as both a Newman projection and as a wedge-dash structure for each enantiomer. Label the configuration of each stereocenter in the resulting hydrobenzoin as either (R) or (S).The sawhorse and Newman projections are also very helpful when working for larger molecules. For example, let’s draw the Newman and sawhorse projections for the following molecule: Now, when asked to draw the Newman projection, a direction must be given. Here you can see that Cl is on the top right (facing the right hand), H is on the top ... Here is one important thing you need to remember when adding the hydrogens or other groups on the zig-zag of the main carbon skeleton. When the zig-zag angle is pointing up, you must point the wedge and dash groups up. When the angle is pointing down, you draw the wedge and dash group down as well: The same principle is applied to larger and ... Translate the given conformer from the wedge-and-dash drawing into its Newman projection. Select the correct Newman projection below and drag the three groups (X, H, and Z) to their correct locations. ciped slacued H X CH3 CH3 There is a hint available. View the hint by clicking on the bottom divider bar. Click on theIt is a diastereomer of "A". Now, let's change the configuration of just "C3" to get Compound "C". This is also a diastereomer of "A". BUT, if we change the configuration of both carbon atoms, we get Compound "D". This is nonsuperimposable on "A". However, it is a mirror image of "A", because both "OH" groups are on dashes instead of on wedges. 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. 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. Let's work through an example, consider drawing a Newman projection by looking at the following wedge-dash diagram from the left hand side.Worksheet on Newman and wedge dash projections Key.

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.$\begingroup$ 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 ...It does not matter if we make the Br a wedge or a dash. It is important to mention the fact that there are two β-hydrogens! The number of β-hydrogens is ultimately what explains the stereochemistry of E2 reactions. To demonstrate this, we will use the Newman and sawhorse projections of the alkyl halide participating in the E2 elimination.When you do this, this will put your aldehyde (CHO) group on the right side. Now, let me show you why the dash/wedge combo is important. Let’s rewrite the structure as follows: We can see that the structure is actually wrapped around like a “broken” circle.
