A.24 and A.26

A.24 Propose a structure consistent with each set of data. . a compound that contains a benzene ring and has a molecular ion at m/z=107 sa hydrocarbon that contains only sp3 hybridized carbons and a molecular ion m/z=84 c a compound that contains a carbonyl group and gives a molecular ion at m/z=114 wa compound that contains C,H,N, and O and has an exact mass for the molecular ion at 101.0841 A.25 A low-resolution mass spectrum of the neurotransmitter dopamine gave a molecular ion at m/z=153. Two possible molecular formulas for this molecular ion are C8H11NO2 and C7H11N3O. A high-resolution mass spectrum provided an exact mass at 153.0680. Which of the possible molecular formulas is the correct one? Fragmentation A.26 Label each of the following in the mass spectrum of hexan-2-ol [CH3CH(OH)CH2CH2CH2CH3] : the molecular ion, the base peak, the fragment resulting from the loss of H2O, and a cleavage fragments.
