Question

What compound is represented by the following NMR spectrum? 

There are 5 signals in the picture I included. They are:

A) 7.2 ppm, 5H, multiplet

B) 4.8 ppm, 2H, singlet

C) 2.6 ppm, 2H, quartet

D) 1.2 ppm, 1H, singlet

E) 1.1 ppm, 3H, triplet

The molecular formula is C9H13N

### NMR Spectrum Analysis for C₉H₁₃N **Summary:** This image depicts a Nuclear Magnetic Resonance (NMR) spectrum for a compound with the molecular formula C₉H₁₃N. The spectrum provides insight into the chemical environment of hydrogen atoms (protons) in the molecule. **Spectrum Details:** - **Horizontal Axis:** The x-axis represents the chemical shift in parts per million (ppm), which indicates the environment of the protons. The range is from 0 to 10 ppm. - **Vertical Axis:** The height of the peaks corresponds to the intensity, reflecting the number of protons contributing to each signal. **Peak Analysis:** 1. **At ~7.3 ppm:** - **Type:** Multiplet - **Integration:** 5 H - **Description:** This region typically indicates aromatic protons, suggesting a benzene ring is present. 2. **At ~4.1 ppm:** - **Type:** Singlet - **Integration:** 2 H - **Description:** A singlet peak indicates protons that are not coupled to any neighboring protons, often seen in methylene groups adjacent to electronegative atoms. 3. **At ~3.2 ppm:** - **Type:** Quartet - **Integration:** 2 H - **Description:** The quartet suggests splitting by three neighboring protons, characteristic of -CH₂- groups in ethyl moieties. 4. **At ~2.5 ppm:** - **Type:** Singlet - **Integration:** 1 H - **Description:** This singlet may indicate a proton in an unusual chemical environment, such as an N-H in amines. 5. **At ~1.2 ppm:** - **Type:** Triplet - **Integration:** 3 H - **Description:** The triplet pattern is typical of methyl groups (CH₃) adjacent to a -CH₂- group, exhibiting coupling to two protons. This spectrum aids in deducing the structure and confirming the presence of functional groups within the C₉H₁₃N compound, aligning with typical NMR interpretations.
