The melting and boiling point of a substance depends on the strength of the intermolecular forces of attraction. Inter-molecular forces of attraction in ionic compounds are strong electrostatic forces between oppositely charged ions which are arranged in the form of a three dimensional lattice. NaCl is an ionic compound.
The intermolecular forces of attraction between ethanol molecules are van der waal's forces of attraction like dispersion forces and a special kind of dipole-dipole attraction which is called hydrogen bonding. 
Hence, both statements are correct and reason is the correct explanation for assertion.
