2. Our knowledge of chair conformations allows us to use them to determine a great deal about a reaction's mechanism. In particular, using a t-butyl group to 'fix' a cyclohexane in a single conformation can help us learn about the spatial requirements and energetics of a reaction. Consider the following two reaction products: CN 'OH 1) NaCN 2) H* 1) NaBH4 2) H3O+ OH Group -H A Value (kcal/mol) Defined as 0.

Question
2. Our knowledge of chair conformations allows us to use them to determine a great deal about a reaction's mechanism. In particular, using a t-butyl group to 'fix' a cyclohexane in a single conformation can help us learn about the spatial requirements and energetics of a reaction. Consider the following two reaction products: CN 1) NaCN 2) H+ OH 1) NaBH4 2) H3O+ OH Group -H -CN A Value (kcal/mol) Defined as 0 0.2 kcal/mol -OH 1.0 kcal/mol c. For any products that do have the most stable conformation, does our understanding of the mechanism allow for ‘thermodynamic control'? d. If one of the products is not the most stable, can you explain the observed product based on ‘kinetic control'? (Does the most easily formed transition state result in the observed product?) Consider the chair-like conformation of the starting material.
