In each of the following groups of compounds, identify the one with the largest heat of combustion and the one with the smallest. (a) Hexane, heptane, octane (b) 2-Methylpropane, pentane, 2-methylbutane (c) 2-Methylbutane, 2-methylpentane, 2,2-dimethylpropane (d) Pentane, 3-methylpentane, 3,3-dimethylpentane (e) Ethylcyclopentane, ethylcyclohexane, ethylcycloheptane
Which would you predict to have the larger (more negative) heat of combustion, cis-1,4-dimethylcyclohexane or trans-1,4-dimethylcyclohexane?
How do you account for the difference in energies between the two staggered conformations of 1,2-dichloroethane? How about for the two eclipsed conformations? Draw all four conformations and, on your drawing, indicate sources of strain – torsional, steric (gauche), steric eclipsed.

Wouldn't the first one be trans-1,2-dimethylcyclobutane because the torsional strain wouldn't allow the carbons to be in the same conformation. Meaning one of the carbons would be up and then the next would be down and so on. Since both methyl groups are equatorial and the first and second carbons are arranged up and down, wouldn't it be trans. Same logic for the second molecule. Carbon 1, which is attached to the methyl is down, carbon 3 which is attached to the methyl should be down also because of torsional strain, and since both methyl are in axial (or equatorial?), it would be cis. Or is it based off of the way the carbons are positioned in the picture?arrow_forward
