Understanding Addition Polymers

What characteristic feature defines an alkene?

• Presence of a carbon-nitrogen triple bond

• Presence of a carbon-carbon single bond

• Presence of a carbon-carbon double bond

• Presence of a carbon-oxygen double bond

What happens to the double bonds in alkenes during polymerization?

• They remain unchanged

• They convert into triple bonds

• They form new double bonds with other atoms

• They break and form single bonds

Why is it impractical to draw all monomers in a polymerization reaction?

• Because they are too small to be seen

• Because they do not form polymers

• Because reactions can involve hundreds of monomers

• Because they are not important in the reaction

What does a repeating unit in a polymer represent?

• The catalyst used in the reaction

• The entire polymer chain

• A group of atoms repeated throughout the polymer

• A single atom in the polymer

How should the bonds of a monomer be drawn in polymerization equations?

• Facing left and right

• Facing up and down

• In a circular pattern

• At random angles

What does the 'n' represent in polymerization reactions?

• The number of carbon atoms

• The number of hydrogen atoms

• The number of monomers or repeating units

• The number of catalysts used

What is the first step in drawing the polymer of butane?

• Identify the single bonds

• Draw the polymer chain

• Identify the double bond

• Count the number of hydrogens

How do you name a polymer formed from butane?

• Butane

• Polybutane

• Polyethylene

• Butylene

What conditions are necessary for addition polymerization reactions?

• Low pressure and no catalyst

• Room temperature and sunlight

• No specific conditions are needed

• High pressure and a catalyst

Where might you see the conditions for polymerization reactions indicated?

• On the monomer

• On the polymer

• On the repeating unit

• On the reaction arrow
