How to draw newman projections from wedge dash.
Here are the pictures of the eclipsed conformations from the video, and our goal is to pick the least stable, but just for practice, let's try drawing all of them as Newman projections. So we'll start with the one on the left here, and we're staring at C2, so that's C2, which we represent by a point.
Label the following Haworth projection as an alpha or beta anomer, and convert the Haworth projection to a six-membered ring with wedges and dashed wedges. Use Newman projection, anddraw all the possible staggered and eclipsed conformers that result from rotation about the C-2, C-3 bond of 2,3-dimethylhexane.Convert the following conformer from its wedge-and-dash representation to a Newman projection. Provide a wedge and dash structure for the following Newman projection. (Image) Consider 1-bromopropane, CH_3CH_2CH_2Br. Draw a Newman projection for the conformation in which -CH_3 and -Br are anti (dihedral angle 180 degrees).Step 1. Number the atoms in the ring (the starting point and the direction doesn't matter). In this case, we will go clockwise: Step 2. Label wedge groups as pointing Up and dash lines as pointing Down. "Up" and "Down" is relative as it depends on the direction you are looking from but let's follow this notation.Drawing Newman Projections. 16m. Barrier To Rotation. 7m. Ring Strain. 8m.

Tear or cut out a piece of paper the shape of this object Æ b. Hold your eye up to your model of ethane to simulate the perspective shown by the Newman projection in Figure. 6.1.
In order to better visualize these different conformations, it is convenient to use a drawing convention called the Newman projection. In a Newman projection, we look lengthwise down a specific bond of interest - in this case, the carbon-carbon bond in ethane. We depict the 'front' atom as a dot, and the 'back' atom as a larger circle.
Interior design projects require careful planning and precise execution. One key aspect of any successful interior design project is creating accurate and detailed floor plans. In ...Example 1. Example 2. Now we will see how to write Newman projection formula from Wedge Dash bond structure. Let’s consider the structure of (2R,3S)-2 …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.Examples showing how to go from a Newman Projection to a line bond Wedge and Hatch structure and vice versa!This organic chemistry video tutorial provides a basic introduction into newman projections. It explains how to draw the newman projections of ethane, butan...
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).
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.

SS's mirror image is RR and they are not superimposable, so they are enantiomers.
