Unformatted text preview: The following GC-MS data were obtained for some common laboratory solvents. The molecular formula of the solvents is given. Based on the molecular formula and the fractionation patterns observed, deduce a structure for the solvents. ***Remember, the molecular ion is equal to the mass of the solvent. The fractionation patterns result when the molecule decomposes in the GC-MS and are directly related to the structure of the molecule. 1. Molecular formula: C 6 H 6 ; molecular ion = 78 2. Molecular formula: CH 2 Cl 2 ; Molecular ion: 84 3. Molecular formula: C 3 H 6 O; Molecular ion: 58 4. Molecular formula: C 3 H 7 NO; Molecular ion: 73...
