Question

Напишіть рівняння реакцій, за допомогою яких можна здійснити такі перетворення: C=CH4=C2H2=C2H4=C2H5Cl

Answer 1

С + 2H₂ --> CH₄
2CH₄ ---> C₂H₂ + 2H₂ (t)
C₂H₂ + H₂ --> C₂H₄ (Kt=Ni.t)
C₂H₄ + HCl --> C₂H₅Cl

Answer 2

Equations for the Given Transformations

To represent the given transformations: C = CH4 = C2H2 = C2H4 = C2H5Cl, we can write a series of chemical reactions. Here are the equations for each transformation:

1. Conversion of C to CH4: - Equation: C + 2H2 -> CH4 - Explanation: Carbon (C) reacts with hydrogen gas (H2) to form methane (CH4) [[1]].

2. Conversion of CH4 to C2H2: - Equation: CH4 -> C2H2 + 2H2 - Explanation: Methane (CH4) undergoes pyrolysis to produce acetylene (C2H2) and hydrogen gas (H2) [[2]].

3. Conversion of C2H2 to C2H4: - Equation: C2H2 + H2 -> C2H4 - Explanation: Acetylene (C2H2) reacts with hydrogen gas (H2) to form ethylene (C2H4) [[3]].

4. Conversion of C2H4 to C2H5Cl: - Equation: C2H4 + HCl -> C2H5Cl - Explanation: Ethylene (C2H4) reacts with hydrogen chloride (HCl) to form ethyl chloride (C2H5Cl) [[4]].

Please note that these equations represent the general reactions for the given transformations. The actual reaction conditions and catalysts may vary depending on the specific reaction setup.
