Accordingly, which is more stable anti or gauche?
In the most stable conformation, the two methyl groups lie as far apart from each other as possible with a dihedral angle of 180 degrees. This particular staggered conformation is called anti. The gauche form is less stable than the anti form by 0.9 kcal/mol due to steric hindrance between the two methyl groups.
Also, which is more stable staggered or eclipsed? In terms of stability, the staggered conformation is more stable than the eclipses. This is for two reasons: 1) Steric hindrance. In the eclipsed conformation, the positioning of the atoms forces them closer together, increasing the amount of steric strain in the molecule.
Similarly, you may ask, which Newman projection has the highest energy?
If we now rotate the front CH3 group 60° clockwise, the molecule is in the highest energy 'eclipsed' conformation, where the dihedral angles are all 0o (we stagger the bonds slightly in our Newman projection drawing so that we can see them all).
What is Newman projection formula?
Newman. projection. 3D structure. A Newman projection, useful in alkane stereochemistry, visualizes the conformation of a chemical bond from front to back, with the front atom represented by a dot and the back carbon as a circle. The front carbon atom is called proximal, while the back atom is called distal.
