Question

Напишіть рівняння реакцій, за допомогою яких можна здійснити такі перетворення: а) С → СН4 → С2Н4 → С2Н4СІ2;

Answer 1

C + 2H2 (t*, p, кат)--> CH4

2CH4 (t*, кат)--> C2H4 + 2H2

C2H4 + Cl2 (свет)--> C2H4Cl2

Answer 2

Equations for the given transformations:

a) The given transformations involve the conversion of carbon (C) to methane (CH4), then to ethylene (C2H4), and finally to ethylene dichloride (C2H4Cl2).

The equations for these transformations are as follows:

1. Conversion of carbon (C) to methane (CH4): - Equation: C + 2H2 → CH4 - This equation represents the reaction where carbon reacts with hydrogen gas to produce methane.

2. Conversion of methane (CH4) to ethylene (C2H4): - Equation: CH4 → C2H4 + 2H2 - This equation represents the reaction where methane decomposes to produce ethylene and hydrogen gas.

3. Conversion of ethylene (C2H4) to ethylene dichloride (C2H4Cl2): - Equation: C2H4 + Cl2 → C2H4Cl2 - This equation represents the reaction where ethylene reacts with chlorine gas to produce ethylene dichloride.

Please note that these equations represent simplified reactions and may not account for specific reaction conditions or catalysts that may be required for the transformations to occur.
