The image contains several chemical reaction equations written on graph paper. The task is to identify and transcribe these equations.

Chemical Reactions from the Image

• 1. Benzene + Cl₂ (AlCl₃ catalyst) → Chlorobenzene + HCl
• Benzene + Cl₂ (light) → Cyclohexane (This reaction is typically UV light, not just 'light')
• Toluene + Cl₂ (AlCl₃ catalyst) → Chlorotoluene + HCl
• Toluene + Cl₂ (light, t°) → Benzyl chloride + HCl
• 2. Benzene + HNO₃ (conc.) (H₂SO₄, t°) → Nitrobenzene + H₂O
• Toluene + HNO₃ (conc.) (H₂SO₄) → Nitrotoluene + H₂O
• 3. Benzene + 1-chloropropane (AlCl₃) → Cumene (Isopropylbenzene) + HCl
• Benzene + 2-chloropropane (AlCl₃) → Cumene (Isopropylbenzene) + HCl
• 4. Cyclohexane + H₂ (Ni, t°, P) → Benzene
• 5. Benzene + Pb(t°) → ? (This reaction is unclear, possibly related to dehydrocyclization or cracking at high temperatures, but the product is not clearly indicated.)
