Question
Identify the commercial preparation(s) of phenol. Chlorobenzene + NaOH at 350 degree C; then H_3 O^+ Benzene + O_2 C_6 H_5 CH(CH_3)_2 + O_2; then H_3 O^+, heat A) and B) A) and C) Phenol is less reactive than expected in Friedel-Crafts acylations for which of these reasons? The acid chloride or anhydride hydrolyzes under the reaction conditions. The electronegativity of the -OH group reduces the reactivity of phenol. Interaction of the -OH group with AlCl_3 forms a species less reactive than phenol. The reaction gives O-acylation only, resulting in an ester. The aromatic ring complexes with AlCl_3 with a resulting decrease in phenol reactivity. Which reagent would you use to carry out the following transformation? tert-butylbenzene rightarrow p-tert-butylbenzenesulfonic acid + o-tert-butylbenzenesulfonic acid HNO_3/H_2 SO_4 tert-C_4 H_9 Cl/AlCl_3 H_2 SO_3/peroxides SO_3/H_2 SO_4 SO_2/H_2 SO_3 Which reagent(s) would you use to synthesize 2- and 4-bromo-l-ethylbenzene from ethylbenzene? N-Bromosuccinimide (NBS), CCl_4, light PBr_3 Br_2, FeBr_3 CH_3 CH_2 Br, AlBr_3 HBr, ROORExplanation / Answer
