Question
The compound has carbon, hydrogen, and oxygen, and the M+ peak is at 88 m/z. The compound loses a fragment very easily to form the peak at 70 m/z, but I’m not sure what exactly is being lost. What is the chemical formula, and the structures for the M+ peak and peaks at 57, 41, and 29 m/z
**Mass Spectrometry Analysis** **A. Fragment Loss Analysis** This compound loses a fragment very easily to form the peak at 70 m/z. What has been lost? **B. Chemical Formula Determination** Determine the chemical formula. Predict the structure for the M+ peak. **C. Structure Prediction** Predict the structures for the peaks at 57, 41, and 29 m/z. **Graph Explanation** The graph displayed is a mass spectrum, which plots relative intensity against the mass-to-charge ratio (m/z). - **X-Axis (m/z):** Represents the mass-to-charge ratio of ionized fragments. - **Y-Axis (Relative Intensity):** Shows the abundance of each ion as a percentage of the most abundant ion peak in the spectrum. Key observations: - There are peaks of varying intensities at m/z values of approximately 29, 41, 57, and 70. - The peak at 70 m/z is significant and indicates the formation of a stable fragment when the original compound undergoes fragmentation. - Other notable peaks are visible at 57, 41, and 29 m/z, suggesting the presence of fragment ions with these m/z values.
