6. The sequence of steps when performing aromatic substitution reactions is critical for the product obtained. In the following four examples, isomers with molecular formula CoHioBrNO: are obtained when benzene is reacted under the conditions shown. In each step assume only one addition will occur and when there is a choice between ortho para substitutions, assume the para product is preferred. Draw the isomers obtained with the following conditions. (24) b. 1) Br2, FeBr 2) 3) HNOs, H SO CI 2) Br2, FeBr 3) NH,NH2, KOH, Î 4 HNO, HSO 4) NH2NMp KOH, Î c. d. 2) HNO, HSO 3) NBS, hv 2) Bra, FeBr )HNO HSO Compound A Compound B Compound c Compound D e.(5) Which isomer would have the fewest number of signals in a proton-decoupled 15C NMR? f.(5) Draw the product obtained if compound C reacts with NaOCHs
