Problem: Consider the following solvent pairs when mixed. Which pair will form two layers? If they form two layers, which solvent would be on top? A. hexanes and waterB. water and methylene chlorideC. hexanes and methylene chlorideD. methanol and hexanesE. ethanol and waterF. acetone and toluene

We’re going to use the theory “likes” dissolving “likes” which states that the solvent can only completely dissolve the solute if they share similar polarity

  • Therefore, compounds with similar polarity can successfully dissolve to create a solution. 
  • Otherwise, layers will form. 
  • The denser of the two liquids will settle at the bottom. 


Intermolecular Forces (IMF) are the attractive forces between 2 molecules.

Ion-dipole

strongest IMF
▪ deals with the attraction between an ion and a polar compound.
