- 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: a. NO NID ALOH 1) NaCN 2) H+ 1) NaBH4 2) H3O+ OH Group -H -CN -OH A Value (kcal/mol) Defined as 0 0.2 kcal/mol 1.0 kcal/mol Draw the most stable chair conformation for each of the two products. b. Based on the A values in the table above, do the two products have the most stable conformation at the new stereocenter?1) RCO H 2) [H₂SOJ. ? Modify the given structure to draw the major product(s). Use the single bond tool to interconvert between double and single bonds. If a racemic mixture of enantiomers is expected, draw both enantiomers.
