What does "aqueous workup" mean? I'm taking a second year organic chemistry and it's a slightly advanced level but I didn't take the 1st year advanced level org.chem. so I may have missed a couple of common terms. What I don't understand is what does workup mean? At the end of some reaction, my prof just says "then you do aq. w/u" and just leaves it at that because he expects the students to know.. Thanks!
