A compound has an M+ ion at 102 amu. There is no M+2 peak. The only IR absorbances in the interpretable region are at 3500 and 2900 cm−1. The 13C NMR spectrum shows three resonances at δ 70 (d), 35 (t), and 30 (t). Draw a structure consistent with this information.

1. A compound composed of carbon, hydrogen & oxygen has a molecular ion at m/z=112 amu in its mass spectrum. The base peak is at m/z=28 amu. The infrared spectrum shows strong absorption in the 2850 to 2980 cm-1 region, and very strong absorption at 1717 cm-1. The 1H nmr shows a single sharp signal at ? = 2.7 ppm, and the 13C nmr has two signals ( ? = 37 & 208 ppm ).

1. An organic compound has a molecular ion at m/z = 90, an M+1 isotope peak at m/z = 91, and an M+2 isotope peak at m/z = 92. The M+1 signal is 5% of the molecular ion’s intensity. The M+2 signal is 4% of the molecular ion’s intensity. What is the molecular formula of the compound? What functional groups are compatible with this molecular formula? Show your reasoning. 2. If the dihedral angle between two nonequivalent vicinal protons is...
