    A dimer is two monomeric subunits that are attached. If you see two subunits in a molecule, it is a dimer. If there are many of that subunit is a polymer.

    I assume all spectra will be straight forward like what does a broad peak above 3000 represent. Alcohol obviously. Or a peak at 17500, ketone. Depending on the molecule, the spectra can almost overlap making it maybe this and maybe that. That's why I assume it'll be obvious.

    u should try to look at the mechanisms when memorizing the rxns b/c many of them have the same mechanisms and its a lot easier that way
