Question 3
1s 3 ORTHO Today we learned about adding a second group to a mono-substituted benzene ring. Any group on a benzene will affect the rate of the reaction (activated or deactivated relative to benzene) and the regioselectivity Where does the electrophile add? Ortho? Meta? Para? Some combination thereof? We found that EDGs (electron-donating groups) direct the electrophile to the ortho and para positions while EWGs (electron-withdrawing groups) direct the electrophile to the meta position. Now, it is time...

Challenge Problem 08.94 9-Borabicyclo[3.3.1]nonane (9-BBN) is a reagent commonly used in the hydroboration of alkynes, but it can also be employed in reactions with alkenes. The following table provides the relative rates of hydroboration (using 9-BBN) for a variety of alkenes (J. Am. Chem. Soc. 1989, 111, 1414-1418) : Relative Reactivity Alkenes CH—CHОBU, 1 CH2 CHBu, 2 CH2-CHCH2OMe, 3 CH CHOAC, 4 CH2 CHCH2OAC, 5 сH—CHCH,CN, 6 CH2 CHCH2C, 7 cis-2-Butene, 8 tans-CH,CH,CHСHC,...

Question1:
Introduction Three aromatic compounds that have ortho-para directing and activating substituents will be brominated. The extent of activation will be judged by the number of bromine atoms that add to the benzene ring in each case. For each of the compounds shown below you will work out if a mono- di- or tri- brominated derivative formed following treatment with acetic acid and bromine in hydrobromic acid. This will be determined by measuring the melting point and interpreting the H...

learned that researchers create various analogues to determine
which structural features are necessary for biological activity and
which are responsible for side effects. The analogues were created
using the molecule shown below. Using the information found in
Tabkw 3, sraw the corresponding analogs #7, 8, and 11.
