Why sodium chloride has high melting point?

Answer :

The sodium chloride has a very high melting point of 801oC is due to the fact the Na and Cl molecules in Na Cl are bounded together by strong electrostatic force of aattraction As for Na to react with Cl then electron ions by sodium is gained by the chlorine atom.


Na+ and Cl- ions being charged attract each other and ionic bond is form between them.


Since the melting and boiling point of the ionic bonds are very high.


Thus NaCl being ionic compound has very high melting point.
