Question

draw the strucutre based off the IR spectrum, 1H NMR spectrum, and 13C NMR spectrum for this compound.

This compound is prepared from the anti-Markovnikov addition of water to phenylacetylene. Its molecular formula is C8H8O.

**Text and Graph Explanation for Educational Website** **1H NMR Spectrum** This spectrum displays the proton nuclear magnetic resonance (NMR) of a compound. The graph plots chemical shift (in parts per million, PPM) on the x-axis, indicative of different proton environments within the molecule. Key Observations: - There are peaks at approximately 10 ppm, 8 ppm, and 4 ppm. - The peak at 10 ppm is marked with an intensity label "22.4". - The peak at 8 ppm is labeled "112.5". - The peak at 4 ppm is labeled "45.0". **13C NMR Spectrum (w/o proton coupled data)** This spectrum represents the carbon-13 NMR of the compound and is also plotted with the chemical shift on the x-axis. This spectrum provides information on the carbon skeleton of the molecule. Key Observations: - Notable peaks occur around 200 ppm, 160 ppm, 140 ppm, 120 ppm, and one around 40 ppm. - A note indicates that there are two peaks at 129 ppm, suggesting overlapping or closely related carbon environments at this chemical shift. Both spectra are crucial for determining the structure of organic compounds and identifying the different types of hydrogen and carbon atoms present.

**IR Spectrum Analysis** The image displays an IR (Infrared) Spectrum graph, which is a tool used to identify and study chemical substances and structures. It represents how much infrared light is absorbed by a sample at different wavenumbers, which relate to specific molecular vibrations. **Graph Details:** - **X-Axis (Wavenumber [cm⁻¹]):** The horizontal axis shows the wavenumber range from 4000 cm⁻¹ to 500 cm⁻¹. Wavenumbers are inversely proportional to wavelength and directly proportional to energy. Peaks in specific regions can indicate functional groups within a molecule. - **Y-Axis (Transmittance [%]):** The vertical axis displays the percentage of transmittance. A high transmittance indicates low absorption, while a low transmittance (or a peak) indicates high absorption of infrared light at that specific wavenumber. **Key Features of the Spectrum:** - **Peaks:** Several distinct peaks are visible across the spectrum. These indicate where the sample absorbs infrared radiation, usually corresponding to the vibrational frequencies of chemical bonds. - **Broad Peak around 3000 cm⁻¹:** This may indicate the presence of O-H or N-H bonds, found in alcohols or amines. - **Significant Peaks between 1600 cm⁻¹ and 600 cm⁻¹:** These regions are typically where bending vibrations of various bonds like C=O, C=C, C-H, etc., occur. This spectrum provides valuable information about the molecular structure, helping chemists identify functional groups and determine the composition of the sample.
