Question:
Use the following NMR- and mass-spectral data to identify the structures of two unknown compounds, A and B.
A: 1H NMR: δ = 0.92 (t, J = 6 Hz, 3 H), 1.32 (broad s, 12 H), 2.28 (broad s, 2 H), and 2.69 (t, J = 7 Hz, 2 H) ppm. Mass spectrum myz (relative intensity) 5 129(0.6) and 30(100).
B: 1H NMR: δ = 1.00 (s, 9 H), 1.17 (s, 6 H), 1.28 (s, 2 H), and 1.42 (s, 2 H) ppm. Mass spectrum m/z (relative intensity) = 129(0.05), 114(3), 72(4), and 58(100).
