An alkene having the molecular formula C,H12 is treated sequentially with ozone (O3) and zinc/acetic acid to give the product/s shown. CH3CH2CH,CH½CH2CH Draw a structural formula for the alkene. You do not have to consider stereochemistry. You do not have to explicitly draw H atoms. • In cases where there is more than one answer, just draw one. P opy aste Previous Next

Draw the structure of the major organic product of the reaction below. CH3 CH₂CHCH₂CH₂CH=CH₂ + CHC13 KOH • Use the wedge/hash bond tools to indicate stereochemistry where it exists. Show stereochemistry in a meso compound. If the reaction produces a racemic mixture, just draw one stereoisomer.

Draw the four major products that form, including stereoisomers, in the bromination of cyclopentene with Br2 and light. Make sure you draw all four bonds at all stereocenters. Br₂ hy

A E OH OH H This is a(n) OH R B F PCC, CH₂Cl₂ H type reaction. The major product if R = CH₂CH3 is compound The major product if R = H is compound G Look at the given reaction and use the letter code corresponding to each compound in the blank to indicate the expected product(s), or fill in the blank with the appropriate vocabulary word or phrase. If a specific stereoisomer (e.g single enantiomer) is formed, select that isomer only. If a mixture of stereoisomers (e.g. racemic or diastereomers) is formed, select the single structure that shows the appropriate mixture (e.g. lines not dashes). If we convert the reagent to Na2CrO4, H₂SO4, H₂O: The major product if R = CH₂CH3 is compound The maior product if R = H is compound ??? OH D H H though compound
