Wondering how to draw Newman projections from a bond line …Because that puts the hydrogen as a dash, so R/S is easy to assign. With two wedges, the structure is (2R, 3R). So the 2R position is fine, and we just switch the wedge at C-3 to a dash, and the structure is correct (2R,3S). To draw the Fischer projection, we do something similar- arbitaritly draw a structure, check R/S, and then adjust as ...This hydrogen and this hydrogen is this hydrogen and this hydrogen. And when you look at it this way, now you say, oh, now I can see how I would draw a Newman Projection. I put this in the front, that in the back.

Why is there such a BIG energy difference between the conformation with a dihedral angle of 0° and 120°? shooting in montgomery al today The gauche interaction occurs in butane occurs when the two methyl groups have dihedral angles of 60° and 300° and arises because the methyl groups are still quite close together (about 3.1 Å, compare to 2.9 Å) for the syn - conformation. The strain energy of the gauche interaction is about 0.9 kcal/mol.This article summarizes the skills sets, problem-solving strategies, and identified student difficulties in representational translation as presented in the literature and offers suggested methods for improving translational accuracy between dash-wedge diagrams and Newman projections.
