Question

Етен →хлороетан → етанол → етен → карбон (IV) оксид​

Answer 1

Ответ:

C₂H₄ + HCl -->C₂H₅Cl

C₂H₅Cl + KOH р-р--> C₂H₅OH + KCl

C₂H₅OH ---> C₂H₄ + H₂O (H₂SO₄,t)

C₂H₄ + 3O₂---> 2CO₂ + 2H₂O

Answer 2

Chemical Reaction Sequence

The chemical reaction sequence you've provided involves several important organic compounds. Let's break it down step by step:

1. Eten to Chloroethane: - The conversion of eten to chloroethane involves the addition of a chlorine atom to the carbon-carbon double bond in eten. This reaction is known as the addition reaction. - The reaction can be represented by the following chemical equation: ``` Eten + Chlorine → Chloroethane ```

2. Chloroethane to Ethanol: - The conversion of chloroethane to ethanol typically involves a substitution reaction where the chlorine atom is replaced by a hydroxyl group (OH). - The reaction can be represented by the following chemical equation: ``` Chloroethane + Hydroxide Ion → Ethanol + Chloride Ion ```

3. Ethanol to Eten: - The conversion of ethanol to eten typically involves the removal of a water molecule (dehydration) from ethanol. - The reaction can be represented by the following chemical equation: ``` Ethanol → Eten + Water ```

4. Eten to Carbon (IV) Oxide: - The conversion of eten to carbon (IV) oxide (carbon dioxide) involves the complete combustion of eten in the presence of oxygen. - The reaction can be represented by the following chemical equation: ``` Eten + Oxygen → Carbon (IV) Oxide + Water ```

Conclusion

The chemical reaction sequence you've provided involves a series of important organic reactions, including addition, substitution, dehydration, and combustion. Each step in the sequence represents a distinct chemical transformation of the starting compound into a different product.
