Construct a simulated 1H NMR spectrum, including proton integrations, for CH3OC(CH2OCH3)3 (see Hint). Drag the appropriate splitting patterns to the approximate chemical shift positions; place the integration values in the small bins above the associated chemical shift. Splitting patterns and integrations may be used more than once, or not at all, as needed. Likewise, some bins might remain blank. Note that peak heights are arbitrary and do not indicate proton integrations.

♦ Relevant knowledge
1H-NMR Spectroscopy
1H-NMR spectrum is employed to study organic compounds. Protons in different magnetic conditions produce a signal in the spectrum. The signal is unique to the proton environment because it is able to be divided. The pattern of splitting of an NMR signal is based on the n+1 rule where it is the number proton pairs that are adjacent to the one being studied. Apart from splits, NMR spectra can give us the number of protons in the environment by calculating the integration coefficients. They are determined by determining the location of the peak.

    Concepts and Reason

    The NMR spectrum of protons:

    •  The proton NMR spectroscopy is one the techniques that can be useful to determine how the chemical will behave.
    •  In 1H-NMR spectrum, peaks can be detected at the time the proton nuclei’s wavelengths are aligned to the wavelengths of the substance nuclei.
    • The same way other techniques like 13CNMR , IR and mass spectroscopy which are available.
    Fundamentals

    * [katex]^{\rm{1}}{\rm{H NMR}}[/katex] Spectroscopy.

    The number of hydrogen atoms attached at a carbon position determines the number of peaks in proton NMR spectrumcopy.

    [katex]\begin{array}{l}\\{\rm{number of line = 2nI + 1}}\\\\{\rm{I = 1/2 for proton}}\\\\{\rm{n = number of hydrogen atoms at adjecent carbon atom}}\\\end{array}[/katex]

    Below is the drawn structure.

    HаС— -CH3З Н2 -с -CH3 HаС- -o- Нас— о -CHз

    The above structure contains three types of protons. Nine hydrogen atoms exhibit identical behavior (methyl atoms), six hydrogen Atoms display identical behavior, while three hydrogen Atoms display identical behavior (methyl group next to oxygen).

    Because none of the types has adjacent protons, three singlet peaks can be observed in proton NMR spectrumtra.
