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)
Need some help understanding these Fill in the major organic product or products for the following reactions. Make sure to indicate stereochemistry where appropriate. H2SO H20 HBr Br2 CH2Cl2 OH OH OH 1) O3 2) DMS Fill in the major organic product or products for the following reactions. Make sure to indicate stereochemistry where appropriate. H2SO H20 HBr Br2 CH2Cl2 OH OH OH 1) O3 2) DMS
For the following reactions fill in the box with the missing major organic product. Make sure to include stereochemistry when appropriate. If a reaction affords a mixture of enantiomers draw only one enantiomer. In the space below the reaction draw a detailed arrow pushing mechanism for that reaction.
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
