How do molecules of ethene combine together to form a poly(ethene) molecule?

In summary, the process of forming a poly(ethene) molecule involves breaking the double bond of ethene molecules and bonding the unpaired valence electrons with those of another group. This is known as polymerization. A helpful resource for understanding this process is the Wikipedia article on polyethylene and a cute video is also available for visual aid.

hi,

i need to explain how molecules of ethene combine together to form a poly(ethene) molecule?

would it be because the double bond is broken and 2 bonds them placed on the outside of the Carbons (C)?

if this is not correct could someone please let me know where I am going wrong!

thanks!

Yes, it goes somewhat on the way you described. The double bond of ethene (ethylene) molecules are broken and the unpaired valence electron(s) get bounded with those of an other group.

See: http://en.wikipedia.org/wiki/Polyethylene

See this video, it is cute!

1. What is ethene and why is it important in the formation of poly(ethene)?

Ethene, also known as ethylene, is a colorless and flammable gas that is commonly used in the production of plastics. It is important in the formation of poly(ethene) because it is the monomer, or building block, for this polymer.

2. How do molecules of ethene combine together to form a poly(ethene) molecule?

The molecules of ethene combine together through a process called polymerization. This involves the joining of many smaller units, or monomers, to form a large compound, known as a polymer. In the case of poly(ethene), the repeating unit of ethene molecules combine through a double bond to form a long chain polymer.

3. What is the chemical structure of poly(ethene)?

The chemical structure of poly(ethene) is a long chain of carbon and hydrogen atoms, with each carbon atom bonded to two other carbon atoms and two hydrogen atoms. This structure gives poly(ethene) its characteristic properties, such as flexibility and durability.

4. How is the production of poly(ethene) controlled to achieve specific properties?

The production of poly(ethene) can be controlled by varying the conditions of the polymerization process, such as temperature, pressure, and catalysts. By adjusting these factors, the size and structure of the polymer chains can be manipulated, resulting in different properties of the final product.

5. What are the common applications of poly(ethene)?

Poly(ethene) is used in a wide range of applications, including packaging materials, plastic bags, bottles, toys, and medical devices. It is also commonly used in the production of pipes, wires, and cables due to its strength and durability. Additionally, poly(ethene) is used in the automotive and construction industries for its lightweight and insulating properties.
