Question
Which of the following crystalline solids have the highest melting point?
Which of the following crystalline solids have the highest melting point?
- Diamond.
- Zinc.
- Sulphur.
- Ice.
Hint:
Melting point is dependent on the force of attraction between the particles.
The correct answer is: Diamond.
- Diamond is the crystalline solid with the highest melting point.
- Crystalline solids are those compounds that have a fixed array usually arranged in an organized manner. They are joined together with the help of strong intermolecular forces of attraction.
- Diamond has the highest melting point. This is because there is a very strong intermolecular force of attraction in it. This force prevents the diamond from melting easily and thus, it requires a high temperature to break those forces and melt it.
A lot of energy is required for the purpose of melting diamond.
