**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.
