Wait - so you took General Chemistry 1 (one semester) - and went ahead and took a year (2 semesters) of organic chemistry?
Hmm, weird.
Anyway, my recommendation, is if you haven't taken General Chemistry 2 (the second part) - is to take it. The Physical Science portion of the MCAT would require knowledge of this area of chemistry. Of course, there si nothing that you can't learn my yourself with a chem textbook.
Inorganic is a branch of chemistry (and despite its name, is not "everything but orgo"). Most likely the "inorganic" course listed is a upper division (still intro) chemistry course for people who have already taken general chemistry. It deals with crystal structures, molecular orbital theory, hybridization, acid/base, etc. Granted, these topics were covered in general chemistry, but these concepts were grossly simplified in general chem. You go into much more detail in Inorganic. It is like Evolution in Biology. In Intro Bio, you learn about evolution. But all the nitty gritty details about evolution is taught in a seperate (but upper division) of Biology (most likely called Evolutionary Biology).
First - both PCHEM and INORGANIC chemistry courses will satisfy your general chemistry requirements for med school. But unless you are a chem or biochem major, WHY TAKE IT?
I have yet been ask in med school to normalize a wave function, or derive Schrodinger's time-independant wave equation (using matrices). I doubt that MCAT would ask people to use a Fourier transform to determine the multiple signals given off by a proton in a high-field NMR machine.
But to answer your original question - Pchem, inorganic, biochem (if taken in the chem dept and listed as a chem class by your school), advance organic, orgometallic, x-ray diffraction, etc. - all will satisfy med school's general chem requirements. But really, it is overkill when you can just take General Chem 2.
