Cоnsider the electrоn impаct mаss spectrum prоvided below. Which of the following stаtements are true? I. The molecule has one chlorine atom due to the 3:1 ratio of the M : (M+2) signalsII. The molecule has one bromine atom due to the 1:1 ratio of the M : (M+2) signalIII. The fragment at 107 m/z is likely formed from loss of an ethyl groupIV. The signal at 57 m/z is due to loss of a methyl group from the molecular ion.V. Because the molecular ion is even, there must be an even # of nitrogen atoms present.
