Problem: Compounds 1 and 2 have the same chemical formula, but different physical properties.The structure of one of the compounds is shown in Box A. In box B, draw the structure of 2.Which structure, the one in Box A or Box B, corresponds to Compound 1? Explain your answer in terms of the intermolecular attractions present in both molecules.

We’re being asked to determine which structure, the one in Box A or Box B, corresponds to Compound 1.


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. 

Hydrogen Bond is the force that exists when H is directly connected to F, O, or N.


Recall that water (H2O) is a polar molecule that exhibits hydrogen bonding, so the soluble compound must exhibit hydrogen-bonding and the slightly soluble compound would be a compound that doesn’t exhibit hydrogen bonding.
