Unformatted text preview: adjacent carbons (vicinal coupling). Schoolery's Rules: finial check on the structure assignment by 1 H NMR 13 C NMR # of resonances symmetry of carbon framework Type of Carbonyl Each piece of evidence gives a fragment (puzzle piece) of the structure. Piece the puzzle together to give a proposed structure. The proposed structure should be consistent with all the evidence....
