For each of the reactions supply the missing final major product(s) in the boxes provided. Clearly show stereochemisty where appropriate. If a reaction produces a mixture of enantiomers draw both. Supply the name of the mechanism (Sn1, Sn2, E1, E2) by which the requested reaction occurs by. РС ОН CH2CI2 E ONA ETOH CHS H2CRO4 (chromic acid)
For each of the reactions supply the missing final major product(s) in the boxes provided. Clearly show stereochemisty where appropriate. If a reaction produces a mixture of enantiomers draw both. Supply the name of the mechanism (Sn1, Sn2, E1, E2) by which the requested reaction occurs by. NaOH 80 °C, H20 Mechanism ОН HCI 0°C, Ether ОН CrO3 H2SO4
5. Predict the major organic products of the following reactions. Show all asymmetric carbons with wedgeldash notation (i.e., as shown in the starting material). If a reaction produces a racemic mixture, show only one of the enantiomers produced. Carefully note the requested reaction mechanism for each reaction. (20 pts) NaOCH3 CH3OH SN2 Br CH3OH SN1 Br NaOCH3 CH3OH E2 Show Zaitsev product Br CH3OH Br E1
(8 pts) For each reaction, predict what mechanism will account for the major product(s) formed and write (SN1, SN2, E1, E2 or N.R.) in the boxes provided. Explanations or drawings are NOT required. 4. а. Н-о Br heat b. OTs NaOEt НOE с. NaCl OTs DMSO d. CI CHон
6) Predict the major product in each of the following reactions and indicate if it came from an Sn1, S2, E1, or E2 reaction. H3C Br NaOme CH3 H2O H Br MeOH 'BUOK H Br DMSO H3C Br NaOme CH3 H20 MeOH H OTS ЕКОН
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.

3. Shown below are a series of reactions. Predict the major product for each of them. Remember, you will need to first decide whether the reaction occurs by an SN2, SN1, E2, or E1 before you can determine what the product will be. Label each as SN2, SN1, E2, or E1. Hint: First decide whether S2/E2 or S1/E1 is favored, and then decide whether the reaction pathway goes by a substitution or elimination reaction. SN2 / SN1 E2/E1 Na DMSO,rt...
In the substitution reactions below, draw the major product in the box provided and indicate in the small box whether the reaction is SN1, SN2, or neither. Be sure to show all stereochemistry. If more than one enantiomer is produced, write "+Enant" in the box with the product. [10] Product SN1/SN2/Neither NaCN Br DMSO NaOEt EtOH Br NaOMe MeOH NaOH Expensive Acetonitrile CH,Br DMF Nat
Complete the following equations by drawing the structure of the product(s) of the reactions, or the missing reactant in the boxes provided. Write the mechanism typw (SN1, SN2, E1, or E2) in the box provided below each arrow. C. HBr (1 Equivalent)_ d. Li NH3, -78 °C Show Stereochemistry e. Ph/ HCEC: DMSO H3C (Show Stereochemistry)
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...
