Polymer Chemistry Concepts

The video tutorial explains the process of addition polymerization using alkenes. It begins with an introduction to polymerization, followed by a detailed explanation of the mechanism where the double bond in alkenes breaks to form polymers. The tutorial covers the formation of polyethene from ethene, the creation of PVC from chloroethene, and the structure of polypropene. It concludes with naming conventions for halogenated alkenes and their resulting polymers.

What happens to the double bond in ethene during polymerization?

• It forms a triple bond.

• It disappears completely.

• It breaks and forms single bonds.

• It remains intact.

What is the repeating unit in polyethene?

• Vinyl chloride

• Chloroethene

• Propene

• Ethene

Which polymer is formed from chloroethene?

• Polyvinyl chloride

• Polyethene

• Polystyrene

• Polypropene

What is the old name for chloroethene?

• Vinyl chloride

• Styrene

• Propylene

What is the modern name for the monomer used to make PVC?

• Vinyl chloride

• Ethene

• Chloroethene

• Propene

What is the shorthand notation used for in polymer chemistry?

• To represent the entire polymer

• To denote the monomer only

• To indicate the repeating unit

• To show the catalyst used

What is the polymer formed from propene?

• Polystyrene

• Polypropene

• Polyvinyl chloride

• Polyethene

What does 'n' represent in the context of polymerization?
