understand a basic chemistry concept (NOT A HOMEWORK QUESTION) BECAUSE no one could explain it to me BECAUSE a certain cougarMD has gotten any lately and decided to close my thread?

How will I ever get into med school now?
Seriously should I just consider post bac programs now?

Should I try to form a relationship with cougar md and get help with my med school admissions and satisfy her cougar needs?

I just wanted some help understanding the concept of like dissolves like, I mean this is an IMPORTANT CONCEPT and is essential to understanding chemistry and thus doing well on the MCAT and getting into med school

Everybody knows organic is probably the most important class for med school admissions...and cougar md comes and smites my thread

she must be having issues 🙁
I got 99 problems but closing innocent threads down aint one 😎

Oh and my question was:
.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?

Polar solvent dissolves polar solute; nonpolar solvent dissolves nonpolar solute. Like dissolves like. Now quite whining and do a Google search.

Go take p-chem, specifically thermo. Learn the 2nd law of thermodynamics. Then everything makes sense. 😉

Oh yeah, and closing thread because of your second post.
