- Give the Major product(s) and name the starting compound with stereochemistry: H2O H2O H2SO4 H,SO, HgSO,arrow_forwardProvide the structure of the product(s) with stereochemisty if appropriate. If multiple products indicate major product or if products are formed in equal amounts. If there is no reaction expected explain why.

Write the reaction and propose a mechanism using curved arrows notation in each step.arrow_forward
- When cyclohexene is treated with m-chloroperbenzoic acid and H,0, trans-cyclohexane-1,2-diol is produced. Propose a mechanism for this reaction, accounting for the observed stereochemistry. Hint: Recall what a МСРВА + Enantiomer H2O "OH peroxyacid does to an alkene.arrow_forwardQ3- Draw the product and write the reagents of the following reactions. When a racemic mixture is formed, you must draw hoth enantiomers and write "racemie" in the box Bra, hv NaCN, DMF Br t-BUOK, t-BUOH NANH, Br NAOCH, CH;NH2 CH,OH Br NaN, NaOCH CH,OH t-BUOK, t-BUOHarrow_forwardb) DRAW THE product of each of the following reactions?

Label the major products. chlorocyclohexane + NaOCH3 in CH3OHarrow_forwardWhich of the following additions to alkenes occur(s) specifically in an anti fashion? I am referring to anti/syn stereochemistry in this question, not the Markovnikov-based regiochemistry.

- Draw the major product or products of each reaction. If the reaction is stereoselective, be certain that your structure(s) clearly indicate the correct stereochemistry. On the lines next to each reaction, indicate if the reaction likely proceeds by an Syl or Sx2 mechanism. H;C H F hexane CH;CH,Br CH; Br CH;OH e CN pentane Br CH; CH;CH, CH; H,0 C1arrow_forwardPlease predict the products for each of the following reactions. Clearly show the regiochemistry (Markovnikov vs anti-Markovnikov) and stereochemistry (syn- vs anti- or both). If a mixture of enantiomers is formed, please draw all the enantiomers.
