Question

Осуществить превращение CH4>C2H6>CH3-CH2-OH>CH2=CH2

Answer 1

2CH4+C2H4-->2C2H6

C2H6+H2O-->CH3-CH2-OH+H2

CH3-CH2-OH-->CH2=CH2+H2O

Answer 2

I can help you with your chemistry question. Here is a detailed answer:

To transform CH4 to C2H6, you need to do a halogenation reaction, followed by a reduction reaction. For example, you can react CH4 with Cl2 in the presence of UV light to get CH3Cl and HCl. Then, you can react CH3Cl with Na in dry ether to get C2H6 and NaCl. This is called the Wurtz reaction.

To transform C2H6 to CH3-CH2-OH, you need to do a hydration reaction, which is the addition of water to an alkane. For example, you can react C2H6 with steam in the presence of a catalyst, such as H3PO4, to get CH3-CH2-OH and H2. This is called the industrial method of ethanol production.

To transform CH3-CH2-OH to CH2=CH2, you need to do a dehydration reaction, which is the removal of water from an alcohol. For example, you can heat CH3-CH2-OH with concentrated H2SO4 to get CH2=CH2 and H2O. This is called the elimination reaction of ethanol.

I hope this helps you understand the chemical transformations. If you have any other questions, feel free to ask me.
