- For problem 8.17, all of the reactions will be SN2. For each reaction, identify and evaluate each nucleophile (strong? weak? Strong or weak as a base?) Also, evaluate each solvent as polar protic or polar aprotic. I recommend drawing the structure of each solvent.

- For each reaction, decide whether substitution or elimination (or both) is possible, andpredict the products you expect. Label the major products. chlorocyclohexane + NaOC(CH3)3 in (CH3)3COHWhen 2-bromo-3-phenylbutane is treated with sodium methoxide, two alkenes result (by E2 elimination). The Zaitsevproduct predominates.(a) Draw the reaction, showing the major and minor products.(b) When one pure stereoisomer of 2-bromo-3-phenylbutane reacts, one pure stereoisomer of the major product results.For example, when (2R,3R)-2-bromo-3-phenylbutane reacts, the product is the stereoisomer with the methyl groups cis.Use your models to draw a Newman projection of the transition state to show why this stereospecificity is observedWhen 2-bromo-3-phenylbutane is treated with sodium methoxide, two alkenes result (by E2 elimination).
