What is Newman projection?
( ′nü·mən prə′jek·shən ) (organic chemistry) A representation of the conformation of a molecule in which the viewer's eye is considered to be sighting down a carbon-carbon bond; the front carbon is represented by a point and the back carbon... Read More »

Which is the correct newman projection?
They are in fact equally correct. We use the Newman projection to simulate transitional isomerism or isomers with different spatial rotations. Since, the only difference of the two Newman projection of your compound is a 120 degrees turn cl... Read More »

How do you convert a newman projection into a?
The hidden C-C bond in the Newman projection will be a vertical line in the Fischer projection. Mentally rotate one of the carbons so that the substituents are eclipsed in the Newman projection, each with one substituent pointing straight d... Read More »

i usually use my model kit or you could change the fisher projection back into a wedge and dash model and then do it from there.

anti- as in this confriguration the two OH molecules are at 180* to each other while in later they r 120* away so less strain in the former one.

Technically speaking, the question did not specify along which axis the Newman projections must be drawn. However, if you were to draw them along the C1-C2 axis (or C3-C4 axis), you would only have two conformations, eclipsed (A&E) and stag...

Start with a circle. Put 3 bonds on the front that are equally spaced around the circle and all meet in the middle. In between each of the first three pairs of bonds, draw three more bonds that stop at the edge of the circle. If you did thi...
