Question
Please assign peaks for this NMR of Butyl naphthyl ether. I don’t know what to do. I’m really stuck on this
The image contains two NMR (Nuclear Magnetic Resonance) spectra. ### Upper Spectrum: - **Horizontal Axis:** The chemical shift is labeled in ppm (parts per million), ranging from approximately 0.5 to 8.5 ppm. - **Peaks:** - Between 7.5 and 8.0 ppm, there are multiple sharp peaks, commonly indicative of aromatic hydrogen atoms in organic compounds. - A significant peak appears around 4.0 ppm, often associated with aliphatic protons adjacent to electronegative atoms. - Smaller clusters of peaks are present between 1.0 and 3.0 ppm, which might signify different types of aliphatic protons. ### Lower Spectrum: - **Horizontal Axis:** The chemical shift is labeled in ppm, covering a similar range from about 0 to 8 ppm. - **Peaks:** - Similar sharp peaks between 7.0 and 8.0 ppm, likely corresponding to aromatic hydrogens. - Prominent singlet or multiplet observed around 2.5 ppm, typical for aliphatic protons near electron-withdrawing groups. - Other peaks are visible below 2.0 ppm and between 0.5 and 1.5 ppm, which might correspond to different kinds of aliphatic hydrogens. ### General Observations: - Both spectra demonstrate numerous peaks across the range, highlighting a complex mixture or a compound with several unique hydrogen environments. - The intensity and splitting patterns reveal details about the number and type of neighboring hydrogen atoms, helping elucidate the molecular structure. This type of analysis is fundamental for identifying and characterizing organic compounds in chemistry.
