Which one of these ionic compounds has the highest lattice energy?
Everyday Science / Chemistry — Multiple-choice practice
- A. NaI
- B. NaBr
- C. NaF
- D. NaCl
Correct answer
NaF
Explanation
Explanation Lattice energy increases with: - Higher charge of ions - Smaller size of ions Among the given, Na⁺ is common. F⁻ is the smallest anion, so NaF has the strongest electrostatic attraction → highest lattice energy.
