Follow the first week of semester, my most unclear point would have to be the the patterns in Mass Spec. plots. This concept was covered on the in class powerpoint. I have trouble determing the possible identities of the compounds simply by looking at the plots. I know there are characteristic patterns associated with each functional group but have to grasp the concept. I know, though that with more practice and studying, I can see a clear correlation in the plots and find a pattern associated with the functional groups.
