Explain in terms of forces between structural units why
a.) NaCl has a higher boiling point than CH3OH

  • chemistry -

    NaCl consists of a three dimensional array of Na^+ and Cl^-. NaCl must be melted to break the crystal structure holding it together, then the ionic forces must be broken in order to bring NaCl to a boil. CH3OH, on the other hand, is a liquid already (no melting required) and to boil it only some hydrogen bonding between the molecules must be overcome.

    Thanks a lot!!!!!!!!!!!!!!!!
