Question

Why does CaO has higher boiling point than HF?

Answer 1

Answer:

CaO is a ionic Compound and hence it has high melting and boiling point

Explanation:

Ionic compounds have high melting and boiling points due to the formation of a strong ionic bond. Due to the high electrostatic force of attraction, high temperature is required to break the bond.
