Question

Which factor is generally responsible for high melting points?

Answer 1

Answer;

Intermolecular forces.

Step-by-step explanation;

• Melting point is the temperature at which a solid melts or a solid changes to a liquid. In liquids melting point is similar to the freezing point.
• Melting point of a substance depends on the molecular composition, force of attraction between molecules and also the presence of impurities.
• A strong force of attraction between molecules results in a higher melting point. Such that stronger intermolecular forces results to a higher melting point.
• For example, the melting point of ionic compounds is higher due to the strong electrostatic forces joining ions.

Answer 2

Strong intermolecular ion-ion forces are responsible for high melting points. Thus the solid state requires close proximity and high order to have high melting point. Hope this answer helps. Good luck!
