Polymers

What are polymers composed of?

• Large units called macromolecules

• Repeating units called monomers

• Individual atoms

• Ionic bonds

Are you enjoying the video lesson?

• Yes

• No

How are the repeating units of a polymer typically represented in a chemical diagram?

• Enclosed in square brackets with a number 'n' outside.

• Enclosed in curved brackets with a number 'n' in the bottom right corner.

• Shown as individual atoms connected by single lines.

• Represented by a single letter 'P'.

What type of bonds are found within a polymer molecule itself?

• Ionic bonds

• Metallic bonds

• Covalent bonds

• Hydrogen bonds

Why are polymers typically solid at room temperature?

• They have strong covalent bonds between polymer molecules.

• They have a high surface area leading to many weak intermolecular forces that require significant energy to overcome.

• They are giant ionic structures with strong electrostatic forces.

• They have very few intermolecular forces between molecules.
