Poly(ethene) is a large molecule that contains a chain of carbon atoms. What type of molecule is it?

Poly(ethene), also known as polyethylene, is a type of polymer. It is a long-chain molecule made up of repeating units called monomers, specifically ethylene (C₂H₄) units. The process of polymerization occurs when many ethylene monomers chemically bond together, forming a large macromolecule.

1. Structure: Poly(ethene) has a linear or branched structure depending on the polymerization conditions. It consists primarily of carbon (C) atoms arranged in a chain, with hydrogen (H) atoms bonded to the carbon atoms.

2. Type of Molecule: As a polymer, poly(ethene) is classified as an organic macromolecule. It is a synthetic polymer, meaning it is man-made, primarily derived from petrochemical products.

3. Properties: Poly(ethene) is known for its versatility, lightweight characteristics, and resistance to chemicals and moisture. It is widely used in various applications, including packaging materials, containers, and plastic bags.

In summary, poly(ethene) is an organic synthetic polymer made of a repeating chain of ethylene monomers, characterized by its long molecular structure and useful physical properties.
