Label the mass spectrum and provide the key characteristics. **Mass Spectrum of p-Bromoacetanilide**The image displays the mass spectrum of p-bromoacetanilide, providing a graphical representation of the relative intensity of ions as a function of their mass-to-charge ratio (m/z).**Graph Explanation:**- **X-axis (m/z):** Represents the mass-to-charge ratio of the ions detected. The range extends from 0 to 220. - **Y-axis (Relative Intensity):** Indicates the relative abundance of detected ions, with a maximum value of 100.- **Peaks:** Numerous peaks appear at specific m/z values, signifying different ion fragments of p-bromoacetanilide. The heights of these peaks represent the relative intensity of each ion fragment.- The most prominent peaks occur around m/z values of approximately 45 and 165-180, indicating these are major fragments in the spectrum.- **Label:** An identifier "MS-NW-0171" is noted near the top left of the graph, likely serving as a reference ID for this specific sample analysis.This spectrum is crucial for identifying structural components and confirming the molecular structure of p-bromoacetanilide.

Mass spectrometry is not a true spectroscopic method as it does not involve any electromagnetic wave. It helps to provide the rough idea of unknown organic compound on basis of the fragmentation in the compound. There is 2 major key characteristic in this spectrum- 1- Bromine has two major isotope which is 79Br and 81Br. So in the mass spectrum we will observe molecular ion peak M and also a M+2 peak in the spectrum. Here the molecular ion peak is 213 and M+2 peak is 215. The molar mass of this compound is 213.98 hence i took it as 214. so i wrote molecular ion peak as 214. but it can be 213 and isotopic peak at 215. 2- The second characteristic peak is heterolytic cleavage of Br atom. here the reduction of 79 in mass clearly indicates that Br atom is fragmented. 171 peak to 92 peak. Hence these two are key characteristic of this spectrum. The fragmentation of this compound is shown in image-
