Hi can you help me with the following question. I don't understand how to answer the question. If someone could tell me the answer for part a of the following sample problem, i would most gladly appreciate it.
Explain in terms of forces between structural units why
a.) NaCl has a higher boiling point than CH3OH
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!!!!!!!!!!!!!!!!
