Question
**Unknown Organic Compound Analysis**

An unknown organic compound is isolated, and various spectroscopic techniques are used to analyze its structure. The compound produces a molecular ion at m/z = 101, indicating its molecular weight. There is no significant M+2 peak. The IR spectrum shows prominent peaks around 2950 cm⁻¹. Notably, there are no peaks above 3000 cm⁻¹, nor around 1600-1800 cm⁻¹ or 1050 cm⁻¹. 

### **1H-NMR Spectrum Analysis:**

The ¹H-NMR spectrum exhibits the following characteristics:
- Two distinct peaks in the region of 0 to 3 ppm:
  - A singlet at around 2 ppm integrating to 2 protons (2H).
  - Another singlet at around 1 ppm integrating to 3 protons (3H).

### **13C-NMR Spectrum Analysis:**

The ¹³C-NMR spectrum exhibits the following characteristics:
- Three distinct peaks:
  - One peak at around 15 ppm.
  - Another peak at around 25 ppm.
  - A third peak at around 45 ppm.

### **Interpretation and Compound Identification:**

The spectral data suggests a simple organic compound, possibly an alkane or aliphatic compound, with no evidence of functional groups like alcohols, carbonyls, or carboxylic acids (due to the absence of peaks in the 1600-1800 cm⁻¹ and >3000 cm⁻¹ regions in the IR spectrum). 

### **Question for Students:**
Based on the provided spectral data:
- **Molecular ion at m/z = 101**
- **¹H-NMR with a singlet at 2 ppm (2H) and at 1 ppm (3H)**
- **¹³C-NMR peaks at around 15 ppm, 25 ppm, and 45 ppm**

**What is the name of this compound? (IUPAC and common name are both acceptable)**

This analytical approach allows students to delve into the interpretation of spectral data to deduce the structure of an unknown organic compound.
