GCSE Chemistry - Addition Polymers & Polymerisation #56

The video tutorial explains how addition polymers are formed using alkenes, focusing on drawing monomers, repeating units, and polymers. It covers the polymerization process, using ethene and butene as examples, and provides guidance on drawing polymer structures. The tutorial also explains how to name polymers and discusses the conditions required for polymerization reactions.

What feature characterizes alkenes and allows them to form polymers?

• Presence of a carbon-oxygen double bond

• Presence of a carbon-nitrogen triple bond

• Presence of a carbon-carbon double bond

• Presence of a carbon-carbon single bond

Why is it more efficient to represent polymerization reactions using repeating units?

• It changes the chemical properties

• It increases the reaction speed

• It simplifies the drawing process

• It reduces the number of atoms needed

What is the correct way to draw the bonds of a monomer in a polymerization reaction?

• Facing up and down

• In a circular pattern

• At outer angles

• Facing left and right

What does the 'N' represent in the context of polymerization reactions?

• The number of carbon atoms

• The number of hydrogen atoms

• The number of monomers or repeating units

• The number of double bonds

In the polymerization of butene, what is the first step in rearranging the atoms?

• Identify the double bond

• Identify the single bonds

• Draw the reaction arrow

• Count the number of hydrogens

How do you name a polymer formed from butene?

• Butene polymer

• Polybutene

• Butene chain

• Butene plastic

What conditions are typically required for addition polymerization reactions?

• Low pressure and high temperature

• Room temperature and sunlight

• High pressure and a catalyst

• Low temperature and no catalyst
