**Chemical Analysis of C₉H₁₀O using NMR Spectroscopy** **Compound Information:** - Formula: C₉H₁₀O - Observation: No exchange with D₂O **NMR Spectroscopy Details:** The provided image is a Nuclear Magnetic Resonance (NMR) spectrum of the compound C₉H₁₀O. The analysis was conducted using deuterated chloroform (CDCl₃) as the solvent, and the spectrum was recorded on a QE-300 spectrometer. **Spectrum Details:** - **X-Axis (Chemical Shift in ppm):** The x-axis is labeled from 0 to 12 ppm (parts per million), indicating the chemical shift. This is a reflection of different hydrogen environments in the molecule. - **Y-Axis (Arbitrary Intensity):** The y-axis displays the intensity of the resonance signals. - **NMR Peaks (Black Lines):** The graph shows multiple peaks corresponding to the different hydrogen (proton) environments within the compound. Each peak's position (chemical shift) can provide insights into the electronic environment and proximity to electronegative atoms or functional groups. - **Integration Curve (Red Line):** The red line is the integration curve, reflecting the area under each peak. This area is proportional to the number of hydrogen atoms contributing to that signal. **Noteworthy Observations:** - Peaks are distributed primarily between 0 and 10 ppm. - The distinct peaks suggest varied environments of hydrogen atoms, potentially indicating different types of hydrogens such as aromatic, aliphatic, or those near electronegative atoms. - No exchange with D₂O implies the absence of exchangeable protons, such as those in alcohols, phenols, or amines, in the compound. This spectrum provides crucial insights into the structural aspects of C₉H₁₀O, which can be further analyzed to deduce the molecular structure and understand the compound’s behavior in different environments.
