The completed reactions are as follows:

a. 2 C₆H₅CHO + NaOH (50%) —(40–50°C)→ C₆H₅COONa + C₆H₅CH₂OH
(Sodium benzoate + Benzyl alcohol)

b. C₆H₅N₂Cl —(Cu₂Cl₂, HCl / 100°C)→ C₆H₅Cl + N₂
(Chlorobenzene + Nitrogen)

c. C₆H₅CH₃ + CH₃Cl —(Dry AlCl₃ / 80°C)→ o-C₆H₄(CH₃)₂ + p-C₆H₄(CH₃)₂ + HCl
(o-Xylene and p-Xylene)

d. C₆H₅OH + 3 HNO₃ —(conc. H₂SO₄)→ 2,4,6-(NO₂)₃C₆H₂OH + 3 H₂O
(Picric acid / 2,4,6-trinitrophenol)
[Note: With dilute HNO₃, a mixture of o-nitrophenol and p-nitrophenol is formed.]

e. C₆H₁₂O₆ —(Zymase / 25°C)→ 2 C₂H₅OH + 2 CO₂
(Ethanol + Carbon dioxide)
