For each of the reactions below, give the structure(s) of the product(s), and be sure to indicate any relative stereochemistry if appropriate. If no reaction is expected to occur under the indicated conditions, then write "no reaction" or NR, and explain why you would expect nothing to occur. Assume 1 equivalent of reagent for all EAS reactions unless told otherwise. а. CO,Me b. Br NaNH2, NH3 c. Br2

Reactions Predict the product or products of the following reactions. If more than one product, indicate which one is the major product, if possible.  Be sure to indicate stereochemistry and regiochemistry, where necessary.  If no reaction, write “no reaction” as the product.

Propose structure(s) for the main organic product(s) formed in each of the following reactions (show stereochemistry of the product where necessary).

3. For each of the reactions below, give the structure(s) of the product(s). Be sure to indicate relative stereochemistry if appropriate. If more than one product is formed, indicate whether they will form in equal amounts or whether one will be the major product. If no reaction is expected to occur under the indicated conditions, then write “no reaction” or NR.

Predict the products of the following reactions. Include stereochemistry when necessary. For reactions with more than one step show the product formed after each step. OH HO X OH O H PCC 1. NaBH4 2. H* 3. H₂SO4, heat and may not be shared, uploaded or distributed Na₂Cr₂O7 H₂SO4, H₂O

For each of the following questions, provide the missing reagents and conditions or predict the MAJOR product. Indicate stereochemistry and identify a racemic mixture if applicable. If no reaction occurs, write out "no reaction". For #li and 1j, work through the entire series of reactions and draw out the final target product. j. I. II. CH3CH₂C(CH3)₂CH₂C1/AIC13 / AIC13 CI III.1) KMnO4/-OH/Na₂CO3/ heat 2) dilute H3O+ IV. NH,NH, / -OH

Predict the major product or provide the reagents in the following reactions . Be sure to show stereochemistry if necessary.
