As we learned in Chapter 4, monosubstituted cyclohexanes exist as an equilibrium mixture of two conformations having either an axial or equatorial substituent. When R = CH2CH3, Keq for this process is 23.When R = C(CH3)3, Keq for this process is 4000. d. For which R is ΔGo more negative? e.How is the size of R related to the amount of axial and equatorial conformations at equilibrium?

For each of the following processes predict the sign of AS for the reaction. In other words, will AS sys be positive (an increase in entropy) or negative (a decrease in entropy)? AS sys is expected to be positive (an increase in entropy) because one molecule is converted into two molecules. AS sys is expected to be negative (a decrease in entropy) because a cyclic compound is converted into acyclic compounds. O AS sys is expected to be positive (an increase in entropy) because an acyclic compound is converted into cyclic compounds. O AS sys is expected to be negative (a decrease in entropy) because two molecules are converted into one molecule.

If a catalyst could be found that would establish an equilibrium between 1,2-butadiene and 2-butyne, what would be the ratio of the more stable isomer to the less stable isomer at 25°C? CH,=C=CHCH, CH,C=CCH, AG° = -16.7 kJ (-4.0 kcal)/mol
