1.benzene + alkene/ halogenoalkane  alkyl benzene *acid catalyst AlCl3 (s)
2.benzene + acylchloride  ketone (benzenone) *acid catalyst AlCl3(s)
3.ketone(2)  benzoic acid *reflux with H2SO4(aq) and KMnO4(aq)
4.benzoic acid + alcohol(ROH)  ester *warm with HCl(aq) catalyst and alcohal *2 reverse the process reflux with HCl(aq) catalyst
5.alkylbenzene(1)  benzoic acid *prolonged reflux with H2SO4(aq) and KMnO4(aq)
*benzoic acid is the product regardless of the length of alkyl chain *separates out as a white crystalline solid
6.alkylbenzene  phenol *industrial route via cumene
7.alkylbenzene  aldehyde (benzenal) *mild oxidation usin MnO2 and dil H2SO4
8.phenol(6)  ester *dissolve phenol in NaOH (aq) and shake with acid anhydride
9.benzene  nitrobenzene *1:1 mix of conc. HNO3 and conc. H2SO4 reflux at 50 – 55°C{nitrating mixture} *if nitrobenzene is being made from alkylbenzene, then the attachment of nitro group ll b at 2 and 4 positions ie 2-nitrobenzene and 4-nitrobenzene
10.nitrobenzene(9)  phenylamine *reflux with tin in HCl(aq)
11.phenylamine(10) + acylchloride/ anhydride amide [benzene with NHCOR group]
12.phenylamine(10)  phenol *warm with HCl(aq) and NaNO2
13.benzene + Br2 (l)  halogenoarenes
*Fe BR3(s) catalyst
*metallic iron can b used but again it’ll react with halide forming FeX3
*with alkyl benzene mono substitution will result and mix of 2/4 – halogeno-alkylbenzne would be produced
14. alkylbenzene  (halogenoalkyl)benzene
*sunlight/ boiling temp and halogen
15. halogenoarenes + KOH  phenol + KCl
*molten KOH + pressure
16. phenol + NaOH  sodium phenoxide + H2O
*can be reversed by adding strong acid
*initially a milky emulsion of phenol in water forms which separates out as a dense, oily liq layer
17. phenol + sodium  sodium phenoxide + H2
*vigorous reaction
18. phenol + 3Br2  2,4,6 – tribromophenol + 3HBr
*decolorizes bromine water to form a white ppt
19. phenol + HNO3  2/4 – nitrophenol + H2O
*gentle heating = mix of 2and 4- nitrophenol forms
*with nitrating mixture it forms 2,4,6-trinitrophenol (picric acid/ TNT)
20. benzoic acid(s) + PCl5(s)  benzonylchloride(l) + HCl(g) + POCl3(l)
21. phenol + benzonylchloride  phenylbenzoate + HCl
*dissolve phenol in NaOH (aq) and shake with benzonylchloride
22. phenylamine + HNO2  phenol + N2 + H2O
*HNO2 used in this reaction is unstable and is made by reacting HCl with NaNO2(HCl + NaNO2HNO2+ NaCl)
23. phenylamine + HNO2 + HCl  phenyldiazonium chloride + 2H2O
*temp below 5°C
24. Phenyldiazonium + phenol  4- hydroxyl phenylazobenzene + H+
*phenyldiazonium acts as an electrophile

Hi, is there a diagrammatic version available? PLUS do you have any information regarding how to answer questions?
