1bromo1chloro2methylpropane NMR
NMR analysis of 1-bromo-1-chloro-2-methylpropane
There is a compound 1-bromo-1-chloro-2-methylpropane, and its NMR spectrum contains rich structural information.
In this compound, hydrogen atoms in different chemical environments show different signals in the NMR spectrum. The hydrogen on the methyl group has a specific range of chemical shifts of the signal peak due to the relatively single chemical environment it is located in. The hydrogen on the submethyl group connected to bromine and chlorine is affected by the electronegativity of the halogen atom, and the chemical shifts move to the low field. Due to the coupling effect of adjacent hydrogen atoms, the signal peak splitting presents a specific law.
The methylhydrogen in the 2-methylpropane part is connected to the main chain in a specific way, and the chemical shift and splitting of its NMR signal peak are also different from other positions of hydrogen atom signals. By carefully analyzing the chemical shift, integrated area and splitting mode of each signal peak in the 1-bromo-1-chloro-2-methylpropane NMR spectrum, the molecular structure can be accurately inferred, and the connection mode and spatial relative position of each atom can be clarified, providing a key basis for the structural identification of organic compounds.
