Organic chem please help 3. Each of the following reactions gives a substitution product. Identify the major product in each case and indicate whether the reaction is likely to proceed via a bimolecular (SN2) or a unimolecular (SN1) mechanism. (8 pts) SO2CF3 Nal a) acetone CH3OH b) OMs 80% H2O CH3CH2OH c) Br NaCN DMF d)
4. Predict the products of the following reactions & indicate whether they are most likely to go through an SN2, SN1, E1, or E2 mechanism. NaCN DMSO NaOH CH3OH heat Only one product is formed in the following E2 elimination reaction. Draw an arrow-pushing mechanism for the reaction and provide the correct product structure. Include a 3-D drawing (chair conformation) displaying proper stereochemistry of the transition state to explain formation of only the major product. CH3 •Br NaOCH3 ~"'CHS
Please show the mechanism showing all possible substitution products. SN1 and SN2 only. Thank you. Determine the major substitution product(s) for each of the following reactions. In addition, please state the mechanism that is employed in the formation of each product. (8 points) Br NaOCH 3 CH3OH H20 Heat
Unambiguously identify the structures of the major products, reactants, or reagents for the following reactions, including stereochemistry when appropriate. Indicate if the reactions undergo E1, E2, SN1, or SN2 mechanism. 1. ?? H2SO4, H20o NaOCH3 CH3OH 2. CI ?? H2SO4, H20 3. t-BuOK t-BuOH 4 CI CN 5. CI XcCH.OH 6. CI
8. complete the following reactions. mention the type of mechanism (SN1,SN2, E1, or E2) that each follows 8. Complete the following reactions. Mention the type of mechanism (SNI, SN2, E1 or E2) that each reaction follows. (4) (CHy)COH 100°C Br a) Cl Xiocn, NaOCH3 Heat CH3 b) Cl CH3ONa CH3OH,100°C CH3
Draw the products for these reactions. In cases where more than one product is formed, identify the major product. Also, in cases where a nucleophilic substitution occurs, identify the mechanism to be either SN1 or SN2 NaBH CH3 OH H3C
Alkyl Halides and their Reactions: Nucleophilic Substitution and Elimination l. Predict the major organic product for each of the following. (1 major structure is all that needed in each case). (3 points each) Br CH3ONa CH3CH2ONa (for "d", show elimination product only, there will also be some substitution) NaOH e, optically active (for "e", show substitution product or products only. If both enantiomers form, draw both) Is the product solution for reaction "e" above racemic or optically active? (1 point...
