Question
Sodium fluoride salt have __________M.P
- 801°C (1,474°F)
- 996°C (1,825°F)
- Both
- None of these
Hint:
Stronger intermolecular forces result in higher melting points.
The correct answer is: 996°C (1,825°F)
- The compound sodium fluoride (NaF) has a higher melting point than sodium iodide (NaI) because the melting point of a compound depends on the intermolecular forces between one molecule and another.
- These are through space interactions and not true bonds.
