From the spectral data that was given, identify the structure of the ester product. The mass is 116 amu and the molecular formula is C6H12O2. Based on your answer what is the structure of the starting alcohol? **Title: NMR Spectrum of Ester Derived from Alcohol D****Introduction:**This page provides an analysis of the NMR spectrum obtained for an ester synthesized from alcohol D. The spectroscopy was conducted using CDCl\(_3\) as the solvent at 400 MHz.**NMR Spectrum Overview:**The NMR spectrum showcases the chemical environment of hydrogen atoms in the ester compound through peaks at various chemical shift values (expressed in ppm). This allows for structural elucidation and identification of functional groups within the molecule.**Spectrum Details:**- **Chemical Shifts:** - A prominent peak at approximately 3.7 ppm with an explicit splitting pattern suggests the presence of protons in an electronegative environment, likely near an oxygen atom, indicative of an ester linkage. - Between 2.0 and 1.0 ppm, multiple peaks show signal splitting, highlighting a complex proton environment, possibly due to methyl or methylene groups. - A sharp peak observed at around 0.9 ppm could denote protons in an alkyl chain terminal methyl group.- **Integration Values:** - Numerical integration values indicate the relative number of protons contributing to each peak: 1.92, 2.94, 1.00, and 6.94. These can be used to deduce the ratio of different types of hydrogen atoms in the molecule.**Conclusion:**The NMR spectrum provides critical insights into the structural features of the ester derived from alcohol D. The identification of distinct chemical environments allows for a better understanding of the esterification process and the resultant molecular structure.**Note:** This interpretation should be complemented with other analytical techniques for comprehensive structural analysis. ### NMR Spectrum Analysis: Ester from Alcohol D**Sample Details:**- **Compound:** Ester from alcohol D- **Solvent:** CDCl₃- **Frequency:** 100 MHz### Spectrum Description**Chemical Shift Values and Peaks:**1. **Peak #1:** - **Chemical Shift:** ~171.24 ppm - **Label:** Ester Carbon - **Explanation:** This peak corresponds to the carbonyl carbon (C=O) in the ester functional group, a characteristic downfield shift due to the carbon being part of a functional group with strong electron-withdrawing properties.2. **Peak #2:** - **Chemical Shift:** ~70.67 ppm - **Explanation:** This peak may correspond to a carbon atom bonded to heteroatoms such as oxygen, typically seen in esters with nearby electronegative elements.3. **Peak #3:** - **Chemical Shift:** ~20.99 ppm - **Explanation:** This peak represents a carbon (likely an alkyl carbon) in the ester, showing typical upfield chemical shifts for carbons not adjacent to strong electron-withdrawing groups.4. **Peak #4:** - **Chemical Shift:** ~18.13 ppm - **Explanation:** This low-field peak is likely from a similar type of alkyl carbon as Peak #3, showing a nearly equivalent chemical environment.5. **Peak #5:** - **Chemical Shift:** ~14.41 ppm - **Explanation:** This represents a carbon typically further removed from electron-withdrawing effects, commonly seen in alkyl chains.**Additional Information:**- **CDCl₃ Peak:** Located typically around 77 ppm, used as an internal standard in the spectrum.### Graph Details- **X-axis (f1):** Represents the chemical shift in parts per million (ppm), ranging from 0 to 180 ppm.- **Y-axis:** Represents intensity, showing the relative strength of each signal in the spectrum.- **Molecular Structure Notation:** A simplified ester structure is sketched next to the peak listings, showing the typical ester linkage.This NMR spectrum provides key information about the carbon framework of the ester compound derived from alcohol D, allowing for identification and analysis of its structure.
