Question

Caco3-cao-cac2-C2H2-c6h6-c6h6oh

Answer 1

CaCO₃ --> CaO + CO₂

CaO + 3C = CaC₂ + CO

CaC₂ + 2H₂O = C₂H₂ + H₂O

3C₂H₂ --> C₆H₆ (Kt=Cакт,t)

C₆H₆ + Cl₂ --> C₆H₅Cl + HCl, C₆H₅Cl  + KOH --> C₆H₅OH + KCl

Answer 2

The series of reactions you've mentioned involves the transformation of calcium carbonate (CaCO3) into benzyl alcohol (C6H6OH). Let's go through each step of the reaction pathway:

1. CaCO3 (Calcium Carbonate): Calcium carbonate is a white, crystalline compound commonly found in rocks and minerals such as limestone, marble, and chalk.

2. CaO (Calcium Oxide): Calcium carbonate (CaCO3) can be heated to high temperatures, causing it to undergo thermal decomposition, resulting in calcium oxide (CaO) and carbon dioxide (CO2) as follows: CaCO3 → CaO + CO2

3. CaC2 (Calcium Carbide): Calcium oxide (CaO) can react with carbon (C) under high temperatures to produce calcium carbide (CaC2): CaO + 3C → CaC2 + CO

4. C2H2 (Acetylene): Calcium carbide (CaC2) reacts with water (H2O) to form acetylene gas (C2H2) and calcium hydroxide (Ca(OH)2): CaC2 + 2H2O → C2H2 + Ca(OH)2

5. C6H6 (Benzene): Acetylene gas (C2H2) can undergo a process called polymerization, where the carbon-carbon triple bond is converted into a benzene ring structure. This reaction results in the formation of benzene (C6H6): 3C2H2 → C6H6

6. C6H6OH (Benzyl Alcohol): Finally, benzene (C6H6) can be further transformed through a chemical reaction called hydrogenation, which involves adding hydrogen (H2) in the presence of a catalyst. This reaction results in the formation of benzyl alcohol (C6H6OH): C6H6 + H2 → C6H6OH

Please note that the reaction pathway you've provided is a simplified overview, and in actual chemical processes, there might be additional steps, side reactions, or specific reaction conditions involved.
