Homework Help: What is the structure?

  1. Mar 18, 2012 #1
    1. The problem statement, all variables and given/known data
    Can someone tell what the structure is by looking at the above spectra?
    Here is spectra:

    2. Relevant equations
    What is the 134 fragment? and what is the structure?

    3. The attempt at a solution
    I see from IR spectrum that I have OH, C-H sp2, C-H sp3, C=C aromatic, C-O groups.
    I see that I have 91, 134, and 149 fragments. I know that 91 is benzene-ch2+ fragment. I don't know what the 134 or 149 fragments are. I know that 149 is actually the whole structure.

    Looking at proton and C13 NMR i see that i have OH, benzene, CH3, CH2, CH groups, not sure if i got all of those groups right.
