Question

Reactions of Arenes

Solve for one major organic product given the following combination of reactants (substrate+reagents).

Substrate: 4-Isopropylbenzoic acid

Reagents: Br2, FeBr3

Answer 1

$$(CH_3)_2 CHC_6H_4CO_2H \quad \xrightarrow{Br_2, FeBr_3}\\ (CH_3)_2 CHC_6H_3BrCO_2H + HBr$$

the major product formed when 4-Isopropylbenzoic acid is acted upon by bromine and iron(iii)bromide is 3-Bromo-4-Isopropylbenzoic acid.
