1 Bromo 2 Methylpropane NMR
Nuclear Magnetic Resonance Study of 1-Bromo-2-Methylpropane
There is something in it, and the name is 1-bromo-2-methylpropane. Now I want to use its NMR sign to explore the molecular secrets.
View the structure of 1-bromo-2-methylpropane, its carbon chain has four, one carbon with bromine, and methyl next to two carbons. In the context of NMR, the resonance of hydrogen nuclei is different.
The hydrogen on the carbon connected to bromine is in a unique chemical environment, and its resonance peak must be different from other hydrogens. Hydrogen on adjacent carbons has different chemical shifts due to the influence of methyl and bromine. Methyl and hydrogen are located in similar environments, and their peaks also have corresponding shapes.
When looking at the number of peaks, we can know the number of hydrogen nuclei in different environments. The split of the peak is generated by the coupling of adjacent hydrogen nuclei, and the adjacent relationship of hydrogen nuclei can be inferred. The area of the peak is proportional to the number of hydrogen nuclei, which shows the ratio of hydrogen nuclei in each environment.
After careful measurement and detailed examination of its NMR map, the layout of hydrogen nuclei in 1-bromo-2-methylpropane molecules can be known, and the microstructure of its structure can be explored. It is of great help to the study of organic chemistry.
