Question

C2H4-C2H6-C2H5Cl-C2H4

Answer 1

Ответ:

С2Н4+Н2=>С2Н6

С2Н6+Cl2=>C2h5cl +HCl

C2H5Cl+KOH=>KCl+H2O+C2H4

Answer 2

The given sequence represents a series of chemical reactions involving hydrocarbons and a chlorinated compound. Let's break down each step:

1. C2H4: This is ethene, a hydrocarbon with the molecular formula C2H4.

2. C2H6: This is ethane, another hydrocarbon with the molecular formula C2H6.

3. C2H5Cl: This is chloroethane, a compound formed by the substitution of a chlorine atom (Cl) for one of the hydrogen atoms in ethane.

4. C2H4: The final product is ethene (C2H4) again.

The overall reaction can be represented as follows:

C2H4 + HCl → C2H5Cl C2H5Cl + C2H6 → C2H4 + HCl

The first reaction involves the addition of hydrogen chloride (HCl) to ethene (C2H4) to form chloroethane (C2H5Cl). The second reaction is a dehydrochlorination reaction, where chloroethane (C2H5Cl) reacts with ethane (C2H6) to produce ethene (C2H4) and hydrogen chloride (HCl) again.

These reactions are known as the "oxychlorination" and "dehydrochlorination" of ethene, respectively. They are commonly used in industrial processes to produce various chlorinated organic compounds.
