Polymerisation of Ethene

This video tutorial covers the polymerization of ethene to form polyethylene. It explains the process of breaking the double bond in ethene under high temperature and pressure to create long chains of polyethylene. The video also discusses how to write polymerization equations, the properties of polyethylene, and the differences between low-density and high-density polyethylene. It concludes with examples of polyethylene's uses in everyday products.

What is the monomer used in the formation of polyethylene?

• Propene

• Ethene

• Methane

• Butene

What is the significance of 'N' in the polymerization equation of ethene?

• It represents the number of carbon atoms.

• It indicates the temperature required.

• It denotes the pressure applied.

• It shows the number of repeat units.

Which type of polymer is formed when the monomer is simply repeated?

• Condensation polymer

• Copolymers

• Addition polymer

• Biopolymer

What is a common use for low-density polyethylene?

• Plastic bottles

• Water pipes

• Folding chairs

• Plastic bags

Which form of polyethylene is known for its higher strength and boiling point?

• Ultra-high molecular weight polyethylene

• Medium-density polyethylene

• High-density polyethylene

• Low-density polyethylene
