3) Another common pattern seen in mass spectra arises in molecules that contain elther chlorine or bromine. Most elements have ane major katope, however, both chlorine and bromine have two common 9 Woadring CHE 332N Spring 2023 isotopes. Chiorine's isotopes are "OC and "CD, which occur naturally in a 3:1 ratio while bromine's isotopes are 3Br and itar, which appear in a ratio of - 1:1. When either of these elements appear on a mass spectrum, there are two peaks appearing for each botope. Since each isotope has a difference in mass of 2 , there are both M and M+2 peaks. For chlorine, the larger peak corresponds to the ACl isotope and is approximately 3 times larger than the M+2 peak due the difference in abundance of "Cl compared to "OC. For bromine, the M and M+2 peaks are approximately the same height. In the belaw spectra, determine if the uninown compounds contain a chlorine or bromine by looking for the M and M+2 ceais. If the urknown contains chlorine or bromine. determine which one is present. 3) Another common pattern seen in mass spectra arises in molecules that contain elther chlorine or bromine.
