1bromo2methylpropane NMR
The NMR analysis of 1-bromo-2-methylpropane
1-bromo-2-methylpropane, its formula is\ (CH_3CH (CH_3) CH_2Br\). The nuclear magnetic resonance (NMR) optical properties of this compound are specific, which can help in its determination.
For nuclear magnetic resonance (\ (^ 1H - NMR\)), the nuclei of different environments in the molecule show different shifts on the optical surface. The nuclei on methyl (\ (- CH_3\)), because of the same environment, show a peak on the optical surface. Due to the spin-spin coupling of the atoms on the carbon phase, this peak may split. In 1-bromo-2-methylpropane, the methyl group of the methylene (\ (-CH -\)) phase, according to\ (n + 1\) (\ (n\) atom on the carbon phase), because the methylene phase contains 1, so the peak of the methyl group is split into two peaks.
The peak of the methylene group (\ (-CH -\)), which is different from the assimilation environment, shows a peak of. Due to the fact that the phase contains methyl, each methyl contains 3, a total of 6, depending on\ (n + 1\), the peak of methyl is divided into seven peaks.
methyl (\ (- CH_2 -\)), due to the bromine atomic phase, and methyl phase, its displacement will be affected by the of bromine atoms., depending on\ (n + 1\), The peak of methyl is divided into two peaks.
However, in the carbon-13 nuclear magnetic resonance (\ (^ {13} C-NMR\)) light, the carbon atoms in the disassimilated environment show disassimilation shifts. There are four disassimilated carbon atoms in the 1-bromo-2-methylpropane molecule, which are divided into methyl carbon, methylenecarbon and methyl carbon in different environments of the bromine phase. Therefore, there are four peaks of disassimilation shifts in the\ (^ {13} C-NMR\) light, which can be used to determine the carbon skeleton of the molecule in one step. On
, the NMR light of 1-bromo-2-methylpropane, including\ (^ 1H - NMR\) \ (^ {13} C - NMR\), can be obtained. Rich information and effective determination of this compound.
