Question

решить цепочку превращений : C2H6=>C2H5CL=>C2H5OH=>CO2

Answer 1

C2H6+Cl2=C2H5Cl+HCl

 

C2H5Cl+KOH=C2H5OH+KCl

2C2H5OH+6O2=4CO2+6H2O

Answer 2

Chain of Transformations: C2H6 => C2H5Cl => C2H5OH => CO2

To solve the given chain of transformations, let's break it down step by step:

1. C2H6 (Ethane) to C2H5Cl (Chloroethane): - Ethane (C2H6) can be converted to chloroethane (C2H5Cl) through a substitution reaction. This reaction involves replacing one of the hydrogen atoms in ethane with a chlorine atom. - The reaction can be represented as follows: ``` C2H6 + Cl2 -> C2H5Cl + HCl ``` - The chlorine atom (Cl) replaces one of the hydrogen atoms in ethane (C2H6), resulting in the formation of chloroethane (C2H5Cl).

2. C2H5Cl (Chloroethane) to C2H5OH (Ethanol): - Chloroethane (C2H5Cl) can be converted to ethanol (C2H5OH) through a substitution reaction. This reaction involves replacing the chlorine atom in chloroethane with a hydroxyl group (-OH). - The reaction can be represented as follows: ``` C2H5Cl + NaOH -> C2H5OH + NaCl ``` - The hydroxyl group (-OH) from sodium hydroxide (NaOH) replaces the chlorine atom in chloroethane (C2H5Cl), resulting in the formation of ethanol (C2H5OH).

3. C2H5OH (Ethanol) to CO2 (Carbon Dioxide): - Ethanol (C2H5OH) can be converted to carbon dioxide (CO2) through a combustion reaction. This reaction involves the reaction of ethanol with oxygen (O2) to produce carbon dioxide and water (H2O). - The reaction can be represented as follows: ``` C2H5OH + 3O2 -> 2CO2 + 3H2O ``` - Ethanol (C2H5OH) reacts with oxygen (O2) to produce carbon dioxide (CO2) and water (H2O).

In summary, the chain of transformations from C2H6 to CO2 involves the conversion of ethane to chloroethane, then chloroethane to ethanol, and finally ethanol to carbon dioxide.
