(a)
Interpretation: The change in enthalpy between the two conformers needs to be determined.
Concept Introduction: The relation between change in standard Gibbs free energy, change in entropy and change in enthalpy is represented as follows:
Here, T is temperature.
(b)
Interpretation: The value of change in standard Gibbs free energy needs to be determined assuming no change in temperature with value of change in standard enthalpy and entropy.
Concept Introduction: The relation between change in standard Gibbs free energy, change in entropy and change in enthalpy is represented as follows:
Here, T is temperature.
(c)
Interpretation: The value of equilibrium constant needs to be determined at given three temperatures
Concept Introduction: The relation between standard Gibbs free energy change and equilibrium constant is as follows:
Here, R is Universal gas constant and T is temperature.

Step 1: Start by drawing all the isomers with double bonds. • Consider constitutional isomers, then stereoisomers. Step 2: Draw all isomers containing a ring. • Consider constitutional isomers, then stereoisomers. Step 2: Next consider isomers containing a ring. The largest ring possible with this molecular formula contains 5 carbons, while the smallest possible ring contains 3 carbons. Draw an isomer containing a 5-carbon ring.
