Exp: Molecular Modeling - newman projection: staggered - newman projection: eclipsed - Newman Projection Conformations and their relative energies [draw a graph] - The gauche conformation of butane occurs when the dihedral angle between at the C1-C2 and C3-C4 is 60 degrees. There is sterric strain in the molecule due the proximity of the two methyl groups. Would the sterric strain in this molecule increase OR decrease C1-C2-C3 [and C2-C3-24] bond angle was increased to more than 109.5...
