Draw a structural formula for the substitution product of the reaction shown below. ● H3C- ● H3C H Br + Na OCCH3 DMF • Use the wedge/hash bond tools to indicate stereochemistry where it exists. If more than one stereoisomer of product is formed, draw both. Separate multiple products using the + sign from the drop-down menu. Products that are initially formed as ions should be drawn in their neutral forms. DMF = dimethylformamide

In addition to organic halides, alkyl tosylates react with organocuprates (R2CuLi) to form coupling products R–R′. When 2° alkyl tosylates are used as starting materials (R2CHOTs), inversion of the configuration at a stereogenic center results. Keeping this in mind, draw the product formed when each compound is treated with (CH3)2CuLi.
Is the product of the reaction below optically active? hv Br₂ OYes, because the reaction produces an optically active product with a chiral center. O No, because the reaction produces a mixture of optically active enantiomers. OYes, because the reaction produces an optically active product with a Br on a terminal carbon. O No, because it is impossible to predict where B r will be added. O No, because the reaction produces a meso compound.
Draw the major products of the SN1 reaction shown below. Use a dash or wedge bond to indicate stereochemistry of substituents on asymmetric centers, where applicable. Ignore any inorganic byproducts. Br CH3CH2OH Select to Draw SN1 Product Drawing
Draw the major product for the reaction, showing the stereochemistry by using wedge bonds. The product will be racemic but show only one enantiomer. Clearly show stereochemistry by drawing one wedged, one dashed and two in-plane bonds per stereocenter. Remember that a hydrogen atom on a chirality center must be shown explicitly and with a wedge or dashed bond. Select Draw Rings More Erase Cl2 CH;CH2OH

Draw the major organic product(s) of the following reaction. H20 Br excess NH3 You do not have to consider stereochemistry. • If no reaction occurs, draw the organic starting material. When Sn1 & E1 pathways compete, show both the substitution and the elimination products. Separate multiple products using the + sign from the drop-down menu. • Do not include counter-ions, e.g., Na*, I', in your answer. ChemDoodle Previou Show Hint
