Bonding in Polymers

Question 1

What are polymers?

Answer 1

• Made by joining together thousands of small, identical molecules (monomers).
• Monomers are often alkene molecules e.g Ethene.

Question 2

Monomers to Polymers:

Answer 2

• Monomers have a double covalent bond.

- Polymers have a single covalent bonds with bonds attached to no element at the ends.

Question 3

How do we draw the repeating unit?

Answer 3

• Show a single covalent bonds between elements.
• Covalent bonds at either side has to extend out the brackets.
• The little n states that the polymer contains a lot of repeating units.

Question 4

What is the first property of Polymers?

Answer 4

• Solids at room temperature.
  (most).
• Intermoleculuer forces of attractions between polymer molecules are relatively strong.
• Takes a lot of energy to break
  = High melting + Boiling Point.
