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. WebThere are three signals in total in the 1 H NMR spectrum. 1,3-dimethylbenzene: H b is situated between two methyl groups, the two H c protons are one carbon away from a methyl group, and H d is two carbons away from a methyl group. Therefore, the four aromatic protons can be divided into three sets. The two methyl groups are equivalent. gaz metan medias fotbal stiri
