Understanding Addition Polymerization

What is the main characteristic of addition polymerization?

• It involves the removal of small molecules like water.

• It uses up all the atoms in the monomers.

• It requires a catalyst to proceed.

• It only occurs at high temperatures.

When drawing a monomer with one C-C double bond, where should the remaining bonds be placed?

• On the right and left of the carbon.

• Randomly around the carbon.

• On top and bottom of the carbon.

• In a circular pattern around the carbon.

Why is it important to avoid placing bonds on the right and left of the carbon in monomers?

• It increases the polymer's melting point.

• It makes the polymer more reactive.

• It can cause confusion when forming the polymer.

• It leads to the formation of unwanted by-products.

What is the purpose of open-ended bonds in polymer structures?

• To represent the presence of impurities.

• To indicate the polymer is incomplete.

• To highlight the starting point of the polymer.

• To show the polymer can expand indefinitely.

What is the shorthand notation for a polymer?

• Drawing the polymer in a circular form.

• Representing the polymer with a single letter.

• Using a single monomer unit with open-ended bonds and 'n'.

• Drawing the entire polymer chain.

In the context of polymers, what does 'n' represent?

• The temperature at which polymerization occurs.

• The catalyst used in the reaction.

• The number of repeating units in the polymer.

• The number of different monomers.

What happens during the radical reaction in polymerization?

• Monomers are broken down into smaller units.

• Double bonds are moved to link monomers.

• Water molecules are released.

• The reaction stops at room temperature.

How does a monomer with two C-C double bonds differ from one with a single double bond?

• It cannot form polymers.

• It requires a different catalyst.

• It has alternating double, single, and double bonds.

• It forms a linear polymer.

What is a copolymer?

• A polymer made from two or more different monomers.

• A polymer that cannot be drawn in shorthand form.

• A polymer that only forms at low temperatures.

• A polymer made from a single type of monomer.

What is the significance of alternating patterns in copolymers?

• They are used to identify impurities.

• They show a specific sequence of different monomers.

• They indicate a random arrangement of monomers.

• They suggest the polymer is unstable.
