19. Which of the following compounds would react fastest with HNO3/H₂SO4? nitrobenzene (PhNO2) A. toluene (PhCH3) B. bromobenzene (PhBr) C. anisole (PhOCH3) D. benzoic acid (PhCOOH) 20. Which series of reactions will convert benzene into p-nitrobenzoic acid? A. CH3Br/AlBr3 followed by HNO3/H2SO4 followed by KMnO4/H₂0 B. HNO3/H₂SO4 followed by KMnO4/H₂O followed by CH3Br/AlBr3 C. KMnO4/H₂0 followed by CH3Br/FeBr3 followed by HNO3/H₂SO4 D. CH3Br/AlBr3 followed by KMnO4/H₂O followed by HNO3/H₂SO4 E. HNO3/H₂SO4 followed by CH3Br/AlBr, followed by KMnO4/H₂0 21.
