<p>Usually Org II and then P Chem I. Org II is not absolutely absolutely necessary, but it should be. As for P Chem I it depends on what was covered in the Thermo class. Was it just an Intro? If there’s no follow on Thermo class, then eventually take P Chem I. The real question is should you take P Chem 2? Hopefully, you have time for all of them.
My question is: why do you have 2 different advisors? Are you a double major?</p>
<p>Take org chem 2, since you learn about nmr techniques in this class and further your knowledge about compounds that you’ll be seeing in your career, however phys chem is similiar to thermo so your not missing out on much, also i believe you’ll be taking other class that deal with concept covered in physical chem.</p>
