Why does NaCl not dissolve in n hexane? Why doesn’t NaCl dissolve in nonpolar solvents such as hexane, C6H14? The lattice energy of NaCl(s) must be overcome to separate Na+ and Cl- ions and disperse them into a solvent. C6H14 is non polar. … Thus, the energy required to separate the ions in NaCl is not recovered in the form of ion- C6H14 interactions.

Why is NaCl soluble in water but not in hexane? Sodium chloride crystals consist of Na+ and Cl- ions. Water is polar, meaning the molecule is not evenly charged (there are small positive and negative charges at each end of the molecule) so it can break apart sodium chloride. Hexane is not polar. It cannot break apart NaCl, so sodium chloride is insoluble in hexane.
