To which of the following compounds does the NMR spectrum belong?
To which of the following compounds does the NMR spectrum belong?
♦ Relevant knowledge
A NMR spectrum is often utilized to determine the degree of reaction development. Typically the NMR of the initial starting substances is taken , and following the process of working up, the pure product’s NMR is determined. If there are no peaks related to the substances that react and new peaks that are characteristic of the product indicate that the reaction has been completed. However when the peaks are different in the expected product , along with the peaks from the beginning materials which indicate the existence of unreacted starting material as well as the product.

The idea is to determine the structure of the compound using [katex]^{\rm{1}}{\rm{HNMR}}[/katex]
The [katex]^{\rm{1}}{\rm{HNMR}}[/katex] signal count
In the [katex]^{\rm{1}}{\rm{HNMR}}[/katex] given signal, total 4 signals were observed
The structure of an unknown compound is thus for the [katex]^{\rm{1}}{\rm{HNMR}}[/katex] given
=> The best option is D
