Concept:

Problem: Five different substances are given to you to be dissolved in water. Which substances are most likely to undergo dissolution in water? Check all that apply.A. lithium iodide, LiIB. hexane, C6H14C. potassium fluoride, KFD. sodium fluoride, NaFE. benzene, C6H6

FREE Expert Solution

Recall that the main idea in dissolution is like dissolves like, which means compounds with the same polarity and intermolecular force can dissolve each other.


Water (H2O) is a polar molecule that exhibits hydrogen bonding.

  • hydrogen bonding exists anytime hydrogen is directly connected to fluorine, oxygen or nitrogen
  • This means that molecules that polar or ionic can dissolve in water.
