From what I'm hearing from my instructor, we will use what we're learning about acids and bases in O chem. This goes for buffers as well.
Chem 2 is a prerequisite for O chem at my school. There is, however, a survey O chem course that one only needs to take Chem 1 as a prerequisite, if that's what you're talking about. Otherwise, I think it would behoove you to take Chem 2 first.
