How bonding and structure are related to the properties of substances
Question
- A. Weak intermolecular forces
- B. Strong attractions between oppositely charged ions
- C. Low energy requirements for state changes
- D. Irregular molecular structures
Answer
The correct option is Strong attractions between oppositely charged ions. This answer is correct because it matches the approved learning objective to explain why ionic compounds usually have high melting points and high boiling points in the subtopic Properties of ionic compounds.
Explanation
The correct option is Strong attractions between oppositely charged ions. Strong attractions between oppositely charged ions is correct because it directly supports the approved learning objective to explain why ionic compounds usually have high melting points and high boiling points. This belongs to the subtopic Properties of ionic compounds within How bonding and structure are related to the properties of substances, 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 Properties of ionic compounds.
Common mistake
Misunderstanding Ionic Compound Properties
Students often think that ionic compounds have high melting and boiling points because of the size of the ions involved.
Emphasize that the high melting and boiling points of ionic compounds are due to the strong electrostatic attractions between oppositely charged ions, not their size.
