4. Draw the Newman projection for the lowest energy rotational isomer of propane. Then draw it for the highest energy rotational isomer. 5. Draw both isomers of 1,2-dimethylcyclopropane (the cis and the trans isomers). Show by means of Newman projections which is more stable. 6. What is a "diaxial" interaction? 7. Cis-1,2-cyclopentanediol melts at about $32^{?}\mathrm{C}$, while the trans-isomer melts at about $55^{?}\mathrm{C}$. Why might this be so? cis-1,2-cyclopentanediol trans-1,2-cyclopentanediol
