Question
- A. Molecules with more bonds are always more reactive
- B. Molecules with symmetrical shapes are less reactive
- C. Molecules with reactive sites exposed to solvent are more reactive
- D. Molecules with larger atomic radii are more reactive
Answer
The correct option is Molecules with reactive sites exposed to solvent are more reactive. This answer is correct because it matches the approved learning objective to explain why the shapes of molecules are important for how substances behave in the subtopic Universal chemistry ideas.
Explanation
The correct option is Molecules with reactive sites exposed to solvent are more reactive. Molecules with reactive sites exposed to solvent are more reactive is correct because it directly supports the approved learning objective to explain why the shapes of molecules are important for how substances behave. This belongs to the subtopic Universal chemistry ideas within Key ideas in chemistry, 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 Universal chemistry ideas.
Common mistake
Misunderstanding Molecular Shapes
Students often think that the shape of a molecule does not affect its behavior or properties.
Emphasize that the shape of a molecule is crucial for its interactions and functions, such as how it fits into biological receptors or its reactivity in chemical reactions.
