Question
identify the strongest intermolecular interactions between each solvent and three solids, as well as the strongest intermolecular interactions between the molecules of each solvent by completing the table below. For hydrogen bonding specify whether the molecules of the solids act as hydrogen bond donor (HBD) or just as hydrogen bond acceptors (HBA).
Water
Methanol
Hexane
Benzophenone
Malonic Acid
Biphenyl
Solvent with itself
Then comparing the strongest intermolecular interaction between the solid and the solvent with the strongest interaction in the solvent itself, predict what the best solvent for each solid and then compare it with the observed results.
Water
Methanol
Hexane
Benzophenone
Malonic Acid
Biphenyl
Solvent with itself
Explanation / Answer
