$NaF$

Vedclass · Answer

(B) The melting point of ionic compounds depends on the lattice energy. $NaF$ has the highest lattice energy among the given halides due to the small size of the $F^-$ ion,which results in a stronger electrostatic attraction with the $Na^+$ ion. While $Na_2S$ is also ionic,$NaF$ is generally considered to have a very high melting point due to its compact crystal lattice structure.
