Unfortunately, I don't know of any schools that offer a degree meant for preparing you to teach chemistry at a college level. I do know that there are programs that would help prepare you to teach math/science education (our schools has such a program). If you want to teach organic at a 4-year accredited college, then it is likely you are going to need a Ph.D in chemistry. However, if you want to teach at a community college, then they might let you teach with a bachelors in chemistry. One possibility would be to major in chemistry and get a master's in education or something related.
Just some random thoughts...
Also, as an FYI, especially at a university, you may not get to dictate what courses you initially teach. They may have you teaching freshman chemistry, or something, and it may not be the same year to year.
