Question

При помощи каких реакций можно осуществить цикл превращений С→СН4→С2Н6→С2Н4→С2Н5ОН→С2Н5ОNa

Answer 1

C + 2H2 ---> CH4
CH4 + Cl2---> CH3Cl+ HCL
2CH3Cl + 2Na ---> C2H6 + 2 NACl
C2H6 ---> C2H4 + H2
C2H4 + H2O ---> C2H5OH
2C2H5OH + 2Na---> 2C2H5ONa + H2

Answer 2

Reactions for the Transformation Cycle

To achieve the transformation cycle from C to CH4 to C2H6 to C2H4 to C2H5OH to C2H5ONa, a series of chemical reactions are required. The reactions involved in this transformation cycle include:

1. Synthesis of Methane (CH4) from Carbon (C): - The synthesis of methane from carbon involves a reaction where carbon combines with hydrogen to form methane. - The chemical equation for this reaction is: C + 2H2 → CH4.

2. Synthesis of Ethane (C2H6) from Methane (CH4): - The synthesis of ethane from methane involves a reaction where methane undergoes a process called steam reforming to produce ethane. - The chemical equation for this reaction is: CH4 → C2H6 + H2.

3. Synthesis of Ethylene (C2H4) from Ethane (C2H6): - The synthesis of ethylene from ethane involves a reaction where ethane undergoes a process called dehydrogenation to produce ethylene. - The chemical equation for this reaction is: C2H6 → C2H4 + H2.

4. Synthesis of Ethanol (C2H5OH) from Ethylene (C2H4): - The synthesis of ethanol from ethylene involves a reaction where ethylene combines with water to form ethanol. - The chemical equation for this reaction is: C2H4 + H2O → C2H5OH.

5. Synthesis of Sodium Ethoxide (C2H5ONa) from Ethanol (C2H5OH): - The synthesis of sodium ethoxide from ethanol involves a reaction where ethanol reacts with sodium metal to form sodium ethoxide and hydrogen gas. - The chemical equation for this reaction is: C2H5OH + Na → C2H5ONa + 1/2H2.

These reactions represent the series of transformations from carbon to sodium ethoxide, each involving specific chemical processes to convert one compound into another.
