Question
What compound gives rise to these spectra?
# Analysis of IR and NMR Spectra ## Infrared Spectrum The infrared spectrum graph displays transmittance (on the y-axis) against wavenumber (cm⁻¹ on the x-axis). Key features include: - A range from approximately 4000 to 400 cm⁻¹. - Notable peaks appear around 3300 cm⁻¹, indicating possible O-H or N-H bonds. - Additional significant peaks are found around 1700 cm⁻¹, which could signify C=O bonds. - Smaller peaks appear between 1600 and 1000 cm⁻¹, often associated with C=C or C-O bonds. ## Nuclear Magnetic Resonance (NMR) Spectrum The NMR spectrum graph shows chemical shift (in ppm) along the x-axis: - It spans from 0 to 10 ppm. - Two prominent peaks: one around 7 ppm, typically associated with aromatic protons. - Another peak is observed around 2 ppm, possibly indicating alkyl groups. These spectral analyses are fundamental for identifying functional groups and molecular structure in organic compounds.
