Newman Projection : These projections are drawn by looking directly along a particular bond in the system (here a C-C bond) and arranging the substituents symmetrically around the atoms at each end of that bond. The protocol requires that the atoms within the central bond are defined as shown below: 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. x First draw the dot and circle to represent the front and back C respectively x Since the front carbon atom has an H atom in the plane of the page pointing up we

Unformatted text preview: can add that first x The back carbon atom has an H atom in the plane of the page pointing down x Now add the other bonds to each C so that it is symmetrical x The groups / bonds (blue) that were forward of the plane of the page in the original wedge-dash diagram are now to our right x Those behind (green) the plane are now to our left x Try the same thing, but looking from the right to generate the other Newman projection Cyclohexane: Drawing cyclohexane so that it looks like a chair can be the key to appreciating the axial and equatorial positions. ... First step is drawing the chair itself. Although the chair "looks better" when slightly angled, it maybe easier to "learn" to draw it with the middle protion horizontal....

What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
