Which one is more stable, cis-1-methyl-3-propylcyclohexane or trans-methyl-3-propylcyclohexane? Draw the most stable chair conformer of trans-1-methyl-2-ethylcyclohexane, show all of the attached hydrogens, and write whether each alkyl substituent is axial or equatorial. (1) Using Newman projections draw the Anti, Syn, and Gauche conformations of 2,5-dimethylheptane with C-3 as the "front" carbon and C-4 as the "back" carbor: (2) Circle the most stable: (3) List the dihedral (torsion) angle found for each structure: (4) Draw a graph of potential energy vs. dihedral angle and identify how each of the above Newman projections corresponds to the valley or peak of the graph (Watch out! does the graph have equivalent peaks and equivalent valleys or not?) (5) Draw the Sawhorse projection for the Anti structure: (6) Draw the wedge-dash 3-dimensional projection for the Syn structure.
