WebOct 28, 2014 · Ernest Z. Oct 28, 2014. The H NMR spectrum of butane shows two signals. The molecule has a plane of symmetry. So C-1 is equivalent to C-4, and C-2 is equivalent to C-3. We should see two signals with area ratios 6:4 or 3:2. The CH₃ signal should appear at about δ 0.9. The CH₂ signal should appear at about δ 1.4. WebOct 3, 2024 · 1. Inductive effects. Consider the molecules tetramethylsilane, ethane, and methylamine. The dipole moment of the C-Si, C-C, and C-N bonds are quite different and are based on electronegativity. We observe this effect in the NMR since TMS will have a shift at 0 ppm, ethane comes at 8.4 ppm, and methylamine is shifted downfield to 26.6 ppm. Thus …
