Identify the unknown organic compound and the fragments in the table below.

- All unknowns contain C and H, and may contain either N,O,Cl, or Br. - Unknowns cannot contain multiple different non-C/H atoms, but might contain two of the same non- C/H atoms. i.e. an unknown cannot contain both O and Br, but could contain two Br atoms. - Fragments in your mass spectrum will be the result of breaking bonds in the parent unknown molecule. Formation of new bonds that were not present in the original compound is extremely rare. The following isotopic ratios might be useful for analysing your spectrum: Hydrogen: 1H(100):2H(0.016)2H can be completely neglected Carbon: 12C(100):13C(1.11) Nitrogen: 14N(100):15N(0.38)15N can be completely neglected Oxygen: 16O(100):17O(0.04)17O can be completely neglected Chlorine: 35Cl(100):37Cl(32.5) Bromine: 79Br(100):81Br(98) Identity of Assigned Unknown
