WebThe nitrogen rule states that organic compounds containing exclusively hydrogen, carbon, nitrogen, oxygen, silicon, phosphorus, sulfur, and the halogens either have (1) an odd nominal mass that indicates an odd number of nitrogen atoms are present or (2) an even nominal mass that indicates an even number of nitrogen atoms in the molecular … WebThe M. + + 1 peak must be the highest mass in the spectrum, an odd-electron ion, and give logical, neutral losses (see 4 and 6 below). If you don’t see an obvious M. + + 1 peak or see multiple peaks in distinct patterns, you may have halogens or other non-C,H,O,N atoms in your molecule. 3. Apply the nitrogen rule. Is M. + odd or even?
