WebIn the eclipsed conformation the H’s are directly behind each other. They are just like the Moon and the Sun during the solar eclipse. Thus the name eclipsed. 😹 In the staggered conformation, the atoms are in-between each other when we look at them directly. The dihedral bond angle in the staggered conformation is 60° while in the ... 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 ...

I think, though I'm not sure, that the higher energy (3.8 kJ/mol) of a gauche conformation (as opposed to a regular staggered) is a result of the same forces that cause higher energy (11 kJ/mol) of two eclipsed methyl groups. designer that begin with mWebTranscribed Image Text: Determine whether each Newman projection is in the staggered or eclipsed conformation.

"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.
