1. (15 points) Draw each of the potential products for each reaction tabel each product as...
For each of the following reactions: (1) Draw all of the organic product(s) that would be formed, and (2) label each product as formed via S1, S2. E1, or E2. For elimination products, label as major or minor. Pay close attention to regiochemistry, stereochemistry, and whether carbocation rearrangements would occur. - DBN ci Br H20 B A C CH3OH acetone NaOH D Br DMSO
3. For each reaction, draw the structure of the major product(s) including stereochemistry where appropriate. Fill n the box below each arrow with the mechanism(s) that will be followed (SN1/E1, SN2, or E2). For SN1/E1 reactions, draw products for both.

Draw the major expected organic product(s) for each of the following reactions. Be sure to indicate stereochemistry when needed. OH 1) TsCl, pyr 2) NaBr Br HS Give neutral product. بیاہ 1) SOCl2, pyridine 2) NaSH OH Br DBU d 1) PBr 3 2) KOt-Bu OH
3. Draw the major and minor products for each of the following reactions. Label major or minor if more than one product. (14 pts) Br DBU 1. TsCl, pyridine CH3CH2OH 2. methoxide ion HO 1. BH, 2.1,0. OH d. HC CHỊCH5OH
3. Draw a structural formula for the major organic product(s) of each reaction and specify the mechanism by which each product is formed (Syl, SN2, E1, or E2). NaOH HO CH3CH2ON CH3CH2OH CH ON CH OH Br CH,OH Na DMSO
1. Predict the major products of each reaction. You do not have to show mechanisms. If you draw the minor product, no credit will be given. Take care to indicate stereocenters where applicable and to draw ALL possible products (.e. enantiomers). No reaction' is an option. PCC KOt-Bu Hy Pd/C NaCN DMSO Bra, CCL

16. Give the major product that you would expect to be formed in each of the following reactions. If you think there is no reaction write NR after the arrow. In each case give the mechanism (SN1, SN2, E1 or E2) by which the product is formed. Also indicate the correct stereochemistry when applicable. Both product and the mechanism should be correct to get credit. No partial credit. Nal -BuOK Acetone t-Buo NaSH DMF Br, H NaOMe DMSO MeOH,rt t-BuOH...
22. Label each reaction below according to which mechanism will give the product the CONDITIONS ,E2 or El (wavy bonds mean a racemic mixture is produced): O. ?CH DMSO, NaOMc H3 Mechanism is: NaOMe, MeOH Mechanism is: KO-t-Bu, DMF CH3 Ha CH3 H3 CHa ??? H2 Mechanism is: CH3 urite the reaction
1. Draw the structure of the principal organic product and predict the stereochemistry to be expected from the reaction of (IR, 2R)-/-bromo-2-methylcyclohexane with each of the following: a. NaOCH, in CH,OH at 60° d. NaNH, in NH, dt 50° b. aqueous CH OH at 140° e. aqueous CH.CH,OH at 25° c. Nal in DMSO at 40° 2. Draw the major product(s) (showing appropriate stereochemistry when necessary) for the following reactions. Indicate the mechanism(s) in operation (SNI,SN2, El. or E2). CH,...
