O...Starting with a Fischer projection, it's not too hard to convert it to a Haworth once you know a few tricks. For C-2, C-3, and C-4, if the OH is on the right hand side of the Fischer, it will be down in the Haworth. If it is on the left hand side of the Fischer, it will be up in the Haworth. If the sugar is D, draw the C-5 CH 2 OH pointing up. On the right, is another drawing of the ethane molecule, but this drawing gives us more information. This is a wedge and dash drawing. Remember, a wedge has a bond coming out at you in space or a bond coming out of the plane of the page. A dash is a bond going away from you in space or a bond going into the plane of the page.

Using these templates, we can take any Newman projection and work backwards to get the corresponding bond-line template, and then draw in the dashes and wedges. Here are the 4 Newman projection patterns, converted into line diagrams. (On the right, you'll see what it looks like when tilted 30°). One important thing to note.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 of propane from the left hand side.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.

You'll get a detailed solution from a subject matter expert that helps you learn core concepts. Question: Draw the Newman projections for BOTH the staggered and eclipsed conformations of the C-1-C-2 bond in ethane. Next, translate the staggered conformation Newman projection to the wedge-dash or sawhorse drawing of ethane.

(<90°) between the wedge and dash. Here's a drawing of propane showing all the hydrogens. I've arbitrarily numbered the carbon on the left as C-1.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.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.

The "12:00 and/or "6:00" of the Newman become the thin lines of the wedge-dash structure. wedges on left dashes on right The dot and circle are shown just to make it clearer which carbon is which. You don't need to actually draw these on your final compound. A staggered Newman becomes a zig-zagged trans thin line. NOTE: We typically do NOT draw ...
