- 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. (g) Sodium methanethiolate (NaSCH3) in ethanolH8. In the partial reduction by NaBH4 of HPK (Hajos-Parrish ketone), the reaction proceeds only to one of the ketones, and the reagent approaches from one of its carbonyl planes, and therefore only one alcohol is selectively obtained. Draw all compounds that can be generated by NaBH4 reduction and explain why the reaction has proceeded selectively.The reaction H2C=CHCH2Br + NaN3 followed by reaction with LiAlH4 yields CH3CH2CH2NH2 H2C=CHCH2NH2 H2C=CHCH2N3 none of the above
