The following NMR corresponds to the molecule depicted below ran without reference. Assign the carbons to the peaks of the spectrum. Do this approximating the shift based on the atoms the Cs are attached to. The question & answer options are attached. The image displays a nuclear magnetic resonance (NMR) spectrum, likely a Carbon-13 NMR, given the parts-per-million (ppm) scale. The spectrum features several peaks corresponding to different carbon environments in the molecule depicted at the top.### Molecular Structure:- The molecule shown contains a silane group (Si) bonded to various carbon atoms. It includes a hydroxyl group (HO) and is labeled: - Carbon 1: adjacent to the hydroxyl group. - Carbon 2: linked to Si. - Carbon 3: branching from Si.### NMR Spectrum Details:- **X-Axis (ppm scale):** Ranges from about 100 ppm to -20 ppm. This scale is typical for Carbon-13 NMR.- **Peaks:** - A peak at **77 ppm**, likely corresponding to a carbon environment, such as CDCl3, the common solvent peak. - A peak at **59 ppm**, possibly associated with Carbon 2 or a similar environment. - A peak at **21 ppm**, which might correspond to Carbon 3. - A peak at **-2 ppm** may be related to TMS (Tetramethylsilane), used as a reference standard.### Dropdown Selection:The dropdown menu allows selecting possible assignments for the peaks:- Options include CDCl3, Carbon 3, MeOD, TMS, Carbon 2, and Carbon 1, assisting in attributing each peak to its respective carbon type in the structure.This NMR spectrum provides critical information for determining the molecular structure by identifying the chemical environment of the carbon atoms in the compound.

13C NMR spectrum of the given compound 2-(trimethylsilyl)ethan-1-olIn 13C NMR spectrum the C attached to the most electronegative neighboring atom are the most deshielded and arise at the most downfield (higher ppm value) and that attached to the least electronegative neighboring atom are the most shielded and arise at the most upfield (lower ppm value). Here the C3 carbons are attached to the least negative Si atom and are highly shielded. So they will appear at extreme upfield. They will be represented by the peak at ~ 2 ppm. The C2 carbon is attached to C1 and Si atom on either side. Thus it is also shielded and will be represented by the peak at 21 ppm. The C1 carbon is attached to C2 and highly electronegative O atom on either side. Thus it is less shielded than C2 and will appear at more downfield than C2. Thus, C1 will be represented by the peak at 59 ppm. The peak at 77 ppm represents the C of the deuterated solvent CDCl3 that has been used as solvent to record the NMR. Answer: peak at 77 ppm : CDCl3 peak at 59 ppm : carbon 1 peak at 21 ppm : carbon 2 peak at ~ 2 ppm : carbon 3
