IB Chemistry: Identification from spectra (12) Answer

Answer to Identification from spectra: Question 12ElementAmount / molSimplest ratioCarbon80.56/12.01 = 6.719Hydrogen7.52 / 1.01 = 7.4510Oxygen11.92 / 16.00 = 0.7451b) The M+ peak at m/z = 134 leads to the conclusion that the molar mass of compound L is the same as the empirical mass and so the molecular formula is C9H10O. The fragment at m/z = 105 suggests loss of an ethyl group to leave C7H5O+, the fragment at m/z =...
