IB Chemistry: Identification from spectra (10) Answer

ElementAmount / molSimplest ratioCarbon54.52/12.01 = 4.542Hydrogen9.17 / 1.01 = 9.084Oxygen36.31 / 16.00 = 2.271b) The M+ peak at m/z = 88 leads to the conclusion that the molar mass of compound J is twice the empirical mass and the molecular formula is C4H8O2. The fragment at m/z 73 suggests loss of a methyl group to leave C3H5O2+, the fragment at 45 could either be due to COOH+ or due to CH3CHOH+ and the fragment at...
