During the process of alpha halogenation of acetophenone in the presence of FeBrg, which statement best describes the most favorable reactive intermediate after step # 1? Choose all that apply. cationic acyl oxygen is formed Danionic acyl oxygenis formed IR signal between 1680-1850 cm1 no IR signal between 1680-1850 cm¹¹ enol is formed alpha halogenation does not occur EAS is preferred t Fe carries a postive charge Fe carries an negative charge Fe remains neutral T
Consider the reaction proposal below and answer the following (Do not consider alpha halogenation). phenol a) 1) 2.0 eq EtCOCL FeCl; b) 1) Acy0, pyr 2) Br 2) Br 3) HCl(aq), heat 3) HCl(aq), heat 4) ECOCL pyridine 1) ACCL pyr 2) Br 3) ECOCL pyr 4) NaOH(aq), beat 5) HCl(aq) to neutralize C OH Br d) No synthesis presented would be effective e) Substitution Pattern Not possible with Phenol, Starting Material a. Which option(s) can generate the target molecule as the major product? a and c b. True or False. The target molecule would have a lower pKa value than the phenol. [Select] c. Using the letters assigned on the molecule which Ar-H signal would be the most deshielded in the ¹H NMR spectrum? C d. Using the letters assigned on the molecule which Ar-H signal would be the most shielded in the ¹H NMR spectrum? b e. Consider the target molecule and describe the splitting pattern of the alpha carbon in the ¹H NMR. doublet
