QUESTION 3:

please help, do not solve/answer if no organic chemistry background. thanks in advance

QUESTION- SEE PHOTO- Annotate with any and all relevant signals. include both wavenumber and the type of stretch/bend responsible for each of the annotated absorption bands. Determine the functional group identity of the experimental IR spectra. Discuss your reasoning.

The image shows an infrared (IR) spectroscopy graph, displaying the transmittance spectrum of a substance labeled "Distillate Group TOJM."

### Description of the Graph:

- **Axes**:
  - The vertical axis represents "% Transmittance," ranging from 56% to 100%.
  - The horizontal axis represents "Wavenumbers (cm⁻¹)," ranging from 4000 cm⁻¹ to 600 cm⁻¹.

- **Graph Characteristics**:
  - The plot shows various peaks, each indicating different vibrational frequencies absorbed by the sample.
  - Key labels with specific wavenumbers are marked on the peaks, which can be attributed to different functional groups present in the substance.

### Notable Peaks and Corresponding Wavenumbers:

- **3374.19 cm⁻¹**: A broad peak typically associated with O-H or N-H stretching.
- **2923.89 cm⁻¹ and 2855.53 cm⁻¹**: Peaks commonly related to C-H stretching in alkanes.
- **1448.24 cm⁻¹**: A peak possibly indicative of C-H bending.
- **1375.13 cm⁻¹, 1288.26 cm⁻¹, and 1210.56 cm⁻¹**: Peaks that can be associated with various bending vibrations or functional groups.
- Other smaller peaks in the range of **1086.62 cm⁻¹ to 620.52 cm⁻¹**: These can indicate complex vibrational modes or molecular interactions.

### Educational Context:

This IR spectrum is utilized to identify functional groups within a molecular structure by analyzing the energy absorption at different wavenumbers. Each peak represents a particular bond or functional group, providing insight into the chemical composition of the sample. Understanding IR spectroscopy is essential for fields such as organic chemistry, material science, and forensic analysis.
