Question

Напишите уравнения хим. реакций, с помощью которых можно совершить след. превращение: CH4->CH3Cl-->C2H6->C2H5Cl->C2H5OH->C4H6 и укажите условия реакций и названия продуктов, пожалуйста, очень нужно

Answer 1

CH4 + Cl2 -> CH3CL + HCL
2CH3Cl + 2Na -> C2H6 + 2NaCl
C2H6 + Cl -> C2H5Cl + HCl
C2H5Cl + NaOH -> C2H5OH + NaCl + H2O
C2H5OH (Al2O3, 500° (это нужно написать над стрелочкой)) -> C4H6 + 2H20 + H2

Answer 2

Chemical Equations and Conditions for the Given Transformation

To achieve the transformation from CH4 to C4H6, several chemical reactions need to take place. Here are the equations for each step of the transformation, along with the conditions and names of the products:

1. CH4 -> CH3Cl (Methane to Chloromethane) - Equation: CH4 + Cl2 -> CH3Cl + HCl - Conditions: This reaction is a substitution reaction that occurs in the presence of ultraviolet (UV) light or heat. It is known as chlorination of methane. - Product Name: Chloromethane

2. CH3Cl -> C2H6 (Chloromethane to Ethane) - Equation: CH3Cl + H2 -> C2H6 + HCl - Conditions: This reaction is a reduction reaction that occurs in the presence of a strong reducing agent, such as lithium aluminum hydride (LiAlH4). - Product Name: Ethane

3. C2H6 -> C2H5Cl (Ethane to Ethyl Chloride) - Equation: C2H6 + Cl2 -> C2H5Cl + HCl - Conditions: This reaction is a substitution reaction that occurs in the presence of ultraviolet (UV) light or heat. It is known as chlorination of ethane. - Product Name: Ethyl Chloride

4. C2H5Cl -> C2H5OH (Ethyl Chloride to Ethanol) - Equation: C2H5Cl + NaOH -> C2H5OH + NaCl - Conditions: This reaction is an alcoholysis reaction that occurs in the presence of a strong base, such as sodium hydroxide (NaOH). - Product Name: Ethanol

5. C2H5OH -> C4H6 (Ethanol to Butadiene) - Equation: 3C2H5OH -> C4H6 + 3H2O - Conditions: This reaction is a dehydration reaction that occurs in the presence of a catalyst, such as sulfuric acid (H2SO4), and at elevated temperatures. - Product Name: Butadiene

Please note that the conditions and names of the products may vary depending on the specific reaction conditions and catalysts used.
