A planar structure for cyclohexane is clearly improbable. The bond angles would necessarily be 120º, 10.5º larger than the ideal tetrahedral angle. Also, every carbon-hydrogen bond in such a structure would be eclipsed. The resulting angle and eclipsing strains would severely destabilize this structure.Draw butane in: Wedge and Dash Representation Newman Projection; Conformational Analysis . Steric strain occurs when atoms are brought too close together. There is an associated cost in energy due to overlapping electron clouds. ... Draw Newman projections for each of the 4 conformations. Fill in the remaining column in the table above.A Newman projection looks at the conformations about a pair of carbon atoms. They can be any two carbon atoms you choose.
