We’re being asked to rank the given pair of compounds in order of increasing strength of solute-solvent interaction.
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, a pure solvent with similar polarity can successfully dissolve a solute to create a solution.
Intermolecular Forces (IMF) are the attractive forces between 2 molecules.
▪ strongest IMF
▪ deals with the attraction between an ion and a polar compound.
• Hydrogen Bonding
Rank the following solute‐solvent interactions in order of INCREASING strength of attraction.
I. K+ in H2O
II. CH3CH2NH2 in H2O
III. CO2 in CCl4
a) I < II < III
b) III < II < I
c) II < III < I
d) I < III < II
e) III < I < II
