Identification from spectra (15) Answer

IB Chemistry: Identification from spectra (15) Answer

ElementAmount / molSimplest ratioCarbon71.93/12.01 = 5.996Hydrogen12.10 / 1.01 = 11.9812Oxygen15.97 / 16.00 = 1.001b) The M+ peak at m/z = 100 is evidence that the molar mass of compound O is 100 g mol-1 and hence its molecular formula is the same its empirical formula, i.e. C6H12O. The fragment at m/z = 71 is due to loss of either –CHO or –CH2CH3 i.e. (M – CHO)+ or (M – C2H5)+ and the fragment at m/z = 29 is...
