IB Chemistry: Identification from spectra (2) Answer

Answer to Identification from spectra: Question 2a) From the elemental analysisElementAmount / molSimplest ratioCarbon15.40/12.01 = 1.282Hydrogen3.24 / 1.01 = 3.215Iodine81.36 / 126.90 = 0.6411b) The M+ peak at 156 is evidence that the molar mass of compound B is 156 g mol-1 and hence its molecular formula is the same as its empirical formula, C2H5I. The fragment at 127 is due to I+ and the fragment at 29 is due to C2H5+....
