Question

  1. A. A small molecule with weak intermolecular forces
  2. B. A giant covalent structure with strong bonds
  3. C. A very large molecule made of repeating units
  4. D. A simple molecule with a fixed number of atoms

Answer

The correct option is A very large molecule made of repeating units. This answer is correct because it matches the approved learning objective to represent covalent bonding in repeating units of polymers using lines and brackets where appropriate in the subtopic Covalent bonding.

Explanation

The correct option is A very large molecule made of repeating units. A very large molecule made of repeating units is correct because it directly supports the approved learning objective to represent covalent bonding in repeating units of polymers using lines and brackets where appropriate. This belongs to the subtopic Covalent bonding within Chemical bonds, ionic, covalent and metallic, so the explanation must stay tied to that curriculum context. The other options are incorrect because they either do not answer this learning objective, use a vague statement, or move away from Covalent bonding.

Common mistake

Misunderstanding Polymer Representation

Students often represent covalent bonding in polymers using only lines without brackets, leading to incomplete structures.

Ensure to use lines for bonds and brackets to indicate repeating units in polymer structures.
