Conformations can be described by dihedral angles, which are used to determine the placements of atoms and their distance from one another and can be visualized by Newman projections. A dihedral angle can indicate staggered and eclipsed orientation, but is specifically used to determine the angle between two specific atoms on opposing carbons. Different conformatio… WebOrganic chemists use line diagrams to represent structures as part of the symbolic code because they are quicker and easier to draw as we can just leave out the C atoms and the H attached to those C atoms because we know to just assume that they are there. This idea also carries over into wedge-hash diagrams.

WebHowever, in butane (C4H10, the one in this video), the front and back carbons in the Newman projections each have a methyl group, and we use those to identify anti or gauche. This means we an also identify one unique eclipsed situation. If the methyl groups eclipse each other, it's referred to as the totally eclipsed conformation (or sometimes ... WebThe overall shape of the molecule is a pyramid with nitrogen at the vertex and a triangular base formed by the three hydrogen atoms.
