### Spectroscopy Assignment #### NMR Spectroscopy Analysis of C₁₀H₁₄ and C₅H₁₂O The image presents two Nuclear Magnetic Resonance (NMR) spectra for two different organic compounds, denoted as C₁₀H₁₄ and C₅H₁₂O. #### Compound 1: C₁₀H₁₄ - **Chemical Shifts and Integrations:** - 7.0 - 6.5 ppm: A large peak with an integration of 5H, likely representing aromatic hydrogens. - 2.1 - 1.4 ppm: Several peaks with integrations annotated with "t", "2H", indicating splitting patterns and hydrogen counts. - 1.0 ppm: A triplet (t) with an integration of 3H, typically indicative of a terminal methyl group (-CH₃). - **Inset:** - An enlarged view of the 5.6 - 1.2 ppm region provides a closer look at the splitting patterns, revealing more detailed information about the hydrogen environments in this range. #### Compound 2: C₅H₁₂O - **Chemical Shifts and Integrations:** - 3.3 ppm: A singlet (1H) likely corresponding to a proton adjacent to an oxygen atom (e.g., -OH). - 1.7 - 1.5 ppm: Multiple peaks with integrations of 2H and 3H, suggesting multiple hydrogen environments, possibly adjacent to alkyl groups. - 0.9 ppm: A large peak with an integration of 6H, indicating the presence of two equivalent methyl groups. #### Graphs and Diagrams: - The upper graph displays the NMR spectrum for C₁₀H₁₄, featuring a range from 0 to 7.8 ppm. Peaks are annotated with hydrogen counts and splitting patterns. - The lower graph shows the NMR spectrum for C₅H₁₂O, also annotated with chemical shifts and integrals, ranging from 0 to 3.3 ppm. Peaks are labeled with the number of hydrogen atoms they represent. Both spectra offer insight into the molecular structure of the respective compounds, highlighting the variety of hydrogen environments and the splitting patterns due to neighboring hydrogen atoms. ### Conclusion
