Question
Common salt has high melting and boiling points.
✓

Answer

- Common salt is an ionic compound. Common salt is solid and hard due to strong electrostatic attraction between oppositely charged $Na +$ and $Cl$ - ions.
- A large amount of energy is required to break the strong intermolecular attraction (strong ionic bond). Hence, common salt has high melting and boiling points.
