In ionic compounds as internuclear distance increases, the melting point decreases so as we move down the group, the melting point decreases.
In ionic compounds as internuclear distance increases, the melting point decreases so as we move down the group, the melting point decreases.
So, as $r_c+r_a$ is greater for $RbBr$ than for $NaF$ so $NaF$ have higher melting point.
