Question

why do the ionic compound have high melting point
​

Answer 1

Ionic compounds are the compounds formed by positively charged cations and negatively charged anions.

The force of attraction between the -ve and +ve ions of an ionic compound is very large and a lot of energy is used up to weaken these forces of attraction. Hence, ionic compounds have a high melting point.

For example, NaCl has a melting point of 801 deg C.

Answer 2

Answer:

Ionic compounds have high melting point because in ionic compound cations and ions are held together by strong electrostatic forces of attraction.

Hence large amount of energy is required to overcome these forces.
