In this problem the H NMR spectrum of styrene oxide shows that protons 1, 2, and 3 all have different chemical shift values. Proton 2 is coupled to both proton 1 (J= 5.8 Hz) and proton 3 (J=2.5 Hz). Draw a scale tree diagram and your best rendering of the resulting peaks for proton 2.
See attached file for full problem description.

Please open up the jpg image which shows the tree diagram and resulting sketch of the nmr spectrum.
The spin-spin coupling pattern of proton 2 can be predicted from the coupling constant, J, measured between protons 2 and 3 and again between ...
