I did a lab where benzophenone was insoluble in water, soluble in methanol, and insoluble in hexane; biphenyl insoluble in water, partially in methanol, and soluble in hexane; and malonic acid was soluble in water and methanol but insoluble in hexane.

How can I explain what I observed?

.I understand that benzophenone is a ketone with 2 phenyl groups and that biphenyl is two phenyls bonded together and that malonic acid has to carboxylic groups.

I understand that benzophnone and biphenyl are NON polar because of the large bulky substituents and are not as polarizable as malonic acid.

But other than that, I'm lost on how to explain what I observed.
I mean all I'm say is like dissolves like but WHAT DOES THIS MEAN?
