PROBLEM Because of their conjugation, azo dyes are highly colored compounds 16-45 and the major artificial color source for textiles and food. Azo dyes are produced by the reaction of aryl diazonium salts with a second aromatic compound. In the product, the aromatic rings are linked by a diazo bridge (-N=N-). From the reactants provided, propose a structure for each azo dye and draw the electron-pushing mechanism. (a) (b) (c) NaO3S OH .. NaO3S CO₂Na CI -NEN NaO3S CH3 OCH3 CL S0₂Na CH3 N=N CL -N=N Methyl Orange Allura Red Lithol Rubine BK

Ibufenac, a para-disubstituted arene with the structureHO2CCH2C6H4CH2CH(CH3)2 , is a much more potent analgesic thanaspirin, but it was never sold commercially because it caused livertoxicity in some clinical trials. Devise a synthesis of ibufenac frombenzene and organic halides having fewer than five carbons.
