Draw the structural formula that is consistent with the of the HNMR spectra shown below
**C₈H₁₀ Spectrum III NMR Analysis** This image displays the Nuclear Magnetic Resonance (NMR) Spectrum for a compound with the molecular formula C₈H₁₀, labeled as Spectrum III. ### Key Features of the Spectrum: 1. **Peaks:** - Two significant singlet peaks ("S") are observable. - The first singlet peak is located around 7.2 PPM (parts per million). - The second singlet peak is located around 2.3 PPM. 2. **X-Axis:** - The horizontal axis represents the chemical shift in parts per million (PPM). - The scale ranges from 0 to 8 PPM, increasing from right to left. This spectrum provides insights into the chemical environment of the hydrogens (protons) within the C₈H₁₀ molecule. ### Interpretation: - The singlet at approximately 7.2 PPM indicates a set of equivalent hydrogen atoms typically found in an aromatic (benzene-like) environment. - The singlet at approximately 2.3 PPM suggests the presence of hydrogen atoms in a different chemical environment, likely part of an alkyl group (e.g., methyl group adjacent to an aromatic ring). This NMR spectrum is a vital tool for deducing the structure of organic compounds, helping to determine the number and type of hydrogen atoms present in distinct chemical environments within the molecule.
