Transcribed Image Text:2) Predicted the diagnostic peaks in the IR spectrum for the starting material, isoborneol, and the product, camphor.
**Infrared Spectrum of Camphor: Detailed Analysis** The image displays the infrared (IR) spectrum of camphor, a terpenoid compound with the molecular formula C₁₀H₁₆O. The spectrum is recorded using a Nujol Mull technique, as indicated in the header. ### Graph Overview: - **X-axis (Wavenumber, cm⁻¹):** The horizontal axis ranges from approximately 4000 cm⁻¹ to 600 cm⁻¹, representing the wavenumber, which is inversely proportional to wavelength. - **Y-axis (Transmittance, %):** The vertical axis indicates transmittance, showcasing how much light passes through the sample. Peaks in the graph correspond to regions of lower transmittance, indicating absorption by the sample at specific wavenumbers. ### Key Features: - **Prominent Peaks:** Notable absorption peaks are observed throughout the spectrum, indicative of various functional groups and molecular vibrations within the camphor structure. - **Functional Group Identification:** The marked peaks are associated with particular molecular bonds: - Around 1700 cm⁻¹ corresponds to C=O stretching, typical for ketones like camphor. - Fingerprint region (1500-800 cm⁻¹) shows complex peaks indicating C-H bending and other characteristic molecular vibrations. ### Tabulated Data: The table beneath the graph shows specific wavenumbers and their assigned values, likely representing peak intensities or assignments. The chart below can be used for quick reference or comparative analysis with known IR spectra to validate compound identification. ### Molecular Structure: - **Diagram:** A structural diagram of camphor is provided, showing its bicyclic structure with a notable ketone group, highlighting its chemical configuration. ### Figure Caption: Figure 23: Infrared Spectra of Camphor This detailed representation aids in understanding the molecular structure of camphor and its characteristic IR absorption features, essential for analytical chemistry and compound verification in educational settings.
