Problem

Rank the following solute‐solvent interactions in order of INCREASING strength of attraction.

I. K+ in H2O

II. CH3CH2NH2 in H2O

III. COin CCl4

 

a) I < II < III

b) III < II < I

c) II < III < I

d) I < III < II

e) III < I < II

Solution

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.

Ion-dipole

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