#### Title: Infrared Spectroscopy Analysis of 2-Octenoic Acid
**Chemical Structure:**
The chemical structure displayed is for 2-Octenoic acid. It contains a chain of carbon atoms with the following composition:
- Chemical formula: \( C_8H_{14}O_2 \)
- Skeletal representation:
\[
\text{CH}_3 \text{--(CH}_2\text{)$_4$---CH=CH--COOH}
\]
**Graph Overview:**
- **Type of Graph:** Infrared (IR) Spectroscopy
- **Axis Details:**
- **Horizontal Axis (x-axis):** Represents Wavenumber (\(\text{cm}^{-1}\)), ranging from approximately 700 to 4000 \(\text{cm}^{-1}\).
- **Vertical Axis (y-axis):** Represents Transmittance (%), varying from 0% to 100%.
**Spectral Peaks and Explanation:**
Several peaks are observable across the spectrum representing specific bond vibrations:
1. **High Wavenumber Region (above 3000 cm\(^{-1}\)):**
- **Broad Peak:** Suggests the presence of O-H stretching, typical in carboxylic acids.
2. **Mid-Wavenumber Region (2000 to 1500 cm\(^{-1}\)):**
- **Sharp Peak around 1700 cm\(^{-1}\):** Indicates C=O stretching, characteristic of carboxylic acids.
3. **Low Wavenumber Region (below 1500 cm\(^{-1}\)):**
- Multiple smaller peaks represent various C-H and C-O bond bending and stretching vibrations.
**Data Table:**
- Contains numerical values, presumably absorption or transmittance at specific wavenumbers. These help in quantitatively analyzing specific bond absorption characteristics, although these values are not explicitly readable in the image provided.
#### Practical Implications:
Understanding this spectrum is crucial for identifying functional groups within the compound and verifying its molecular structure as 2-Octenoic Acid. This analysis is integral to fields like organic chemistry and pharmaceuticals where molecular identification is pivotal.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F824b66ab-910a-4d71-9f1f-531029482f59%2Fde3d75cd-84dc-4a01-8375-a3aee61d805c%2Fsrm98q_processed.jpeg&w=3840&q=75)
