1.  Draw the Lewis structures of the three possible compounds with a molecule formula C₃H₈O.


2.  Sketch the C-13 NMR you would expect for each of the structures in #1.


3.  A compound with the molecular formula C₃H₈O₂ has a C-13 NMR of  with 2 peaks.  The peak with the higher chemical shift is twice the intensity of the lower chemical shift peak. What is the structure of the molecule?
