Question
In a diagram of a polymer, what features would indicate that it is a polymer rather than a small molecular substance?
Answer
A polymer diagram would show long chains of atoms with repeating units, while a small molecular substance would typically be represented as a smaller, discrete group of atoms. The presence of covalent bonds linking many atoms in a continuous structure indicates a polymer.
Explanation
This question assesses the ability to differentiate between polymers and small molecular substances based on structural features. The answer emphasizes the size and bonding characteristics that are unique to polymers.
Common mistake
Misidentifying Polymers
Students often confuse polymers with small molecules, failing to recognize the size and structure differences in diagrams.
Focus on identifying the repeating units and the large size of polymers in diagrams, and compare them to the simpler structures of small molecules.
