Do i need specific values to answer this question? If so what values and could you explain?

6 In evaluating hybridization effects between the anti and eclipse conformers of the hydrocarbon substituents, raw the conformer pair equilibria (i.e., A-A', B-B' C-C') for each compound given immediately below, and construct a relative energy-conformational progress diagram by overlaying the relative energy plot of each conformer pair. Note, use the diagram immediately below as a guide. In addition, briefly explain which equilibria will have the largest free energy difference between the two complimentary conformers. CH H H H H H H L H H H HC Conformational Progress

Explanation / Answer

In conformational analysis, going with the steric bulk "A" values given for cyclohexane and following the same principle here, ethane link would have highest steric bulk in eclipsed form as compared to staggered form. The lowest steric bulk would be observed for acetylene linkage due to lowest number of hydrogens on it. Therefore, the greatest free energy difference would be observed between conformer pair A-A'

drawn below are the conformers and the relative energy diagrams.
