Question

The compound C5H10O has the following H1-NMR chart, what is the possible structure of the compound? Identify the H-protons. 

This image displays a nuclear magnetic resonance (NMR) spectrum, typically used to analyze the chemical structure of organic compounds. ### Key Features of the NMR Spectrum: 1. **X-Axis (f1 in ppm):** - This represents the chemical shift in parts per million (ppm), which provides information about the electronic environment surrounding the nuclei, often used to identify functional groups within a molecule. - The range shown is from -1.5 to 9.0 ppm. 2. **Y-Axis (Intensity):** - This indicates the signal intensity or peak height, which correlates to the number of nuclei generating the signal. 3. **Peaks:** - The spectrum shows multiple peaks clustered in two main regions, around 1.0 and 2.0 ppm. - Peaks at approximately 2.22, 2.30, 2.38, and 2.47 ppm indicate chemical shifts typical of certain methyl or methylene groups. - Peaks around 0.88, 0.96, 1.04 ppm are likely indicative of other alkyl groups. 4. **Peak Splitting and Multiplicity:** - Match peaks with their corresponding splitting patterns, such as singlets, doublets, triplets, etc. The degree of splitting provides insights into the number of adjacent hydrogen atoms. 5. **Integration Curves:** - The green integration curves below the peaks measure the area under each peak. This area is proportional to the number of hydrogen atoms contributing to that peak, useful in determining the hydrogen to carbon ratio. 6. **Coupling Constants:** - The horizontal blue markers indicate the coupling constants, which are the distances between split peaks, often measured in Hertz (Hz). This NMR spectrum can be used to deduce molecular structures by analyzing the chemical shifts, peak multiplicities, and integration values.
