Question
Can someone explain how to do an NMR Spec like this, better refurred to it as Spectroscopy unknown.
I got a pop up that said this might be graded.... I legit got it off of a practice website and I can send the link here: https://www.nmr.tips/indexe.html if you guys really need to know (Sadly you have to pay to get the solutions and I already have a subscription here.)
![### Spectroscopy Unknown
The spectra and data provided below were obtained from a pure organic molecule.
#### Mass Spectrum (not shown):
- **Mass [M] = 177** (100%) m/z
#### IR Spectrum (not shown):
- **Key Peaks (cm⁻¹):** 3200 (sh m), 3060, 2981, 1685, 1600, 1495 (all listed peaks are strong (s) unless otherwise indicated)
### ¹H NMR Spectrum (400 MHz, CDCl₃, 25 °C):
- **0-2 ppm:**
- Single peak at approximately 0.9 ppm (6H), labeled as a singlet (s).
- **2-4 ppm:**
- Multiplet (m) at approximately 2.5 ppm (3H).
- **6-8 ppm:**
- Doublets (d) at approximately 7.2 ppm and 7.5 ppm (each 2H).
- **8-10 ppm:**
- Broad singlet (br s) at approximately 9.8 ppm (1H).
**Integration:**
- Indicates the number of hydrogens: 1H, 2H, 3H, and 6H.
### ¹³C NMR Spectrum, Proton-Decoupled (125 MHz, CDCl₃, 25 °C):
- **15-80 ppm:**
- Peaks at approximately 22 ppm and 44 ppm, labeled as CH₃ and CH, respectively.
- **100-140 ppm:**
- Peaks at approximately 120 ppm (CH) and 130 ppm (CH).
- **135-180 ppm:**
- Peaks at approximately 135, 145, and 155 ppm, labeled as C.
Each peak is marked with either (CH₃), (CH), or (C) to indicate the type of carbon environment.
This data is crucial in determining the structure of organic molecules, linking specific hydrogen and carbon environments to their respective NMR peaks.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F56b89a6c-6ca3-4f25-9a44-1409c69966fc%2F1db2edac-2262-444c-be73-7ee4c567d7be%2Flfo12ek_processed.png&w=3840&q=75)
