nde<\/span>: N\u00famero de dobles enlaces (se omite si es cero).<\/li>\n
nC<\/span>: N\u00famero de \u00e1tomos de carbono – 1 (se omite si es cero).<\/li>\n

nFl<\/span>: N\u00famero de \u00e1tomos de fl\u00faor.<\/li>\n
nCl<\/span>: N\u00famero de \u00e1tomos de cloro reemplazados por \u00e1tomos de bromo (se le a\u00f1ade el prefijo B), o \u00e1tomos de yodo (se le a\u00f1ade el prefijo I) (se omite si es cero).<\/li>\n
a<\/span>: Letra o letras a\u00f1adidas para identificar los is\u00f3meros. En el caso de un haloalcano de dos carbonos, el is\u00f3mero “normal”, sin letra, para una numeraci\u00f3n es aquel que tiene la menor diferencia de masas entre los carbonos. A continuaci\u00f3n las letras a, b, etc. son adjudicadas sucesivamente a cada is\u00f3mero conforme la diferencia de masas se aleja de la del \u201cnormal\u201d.<\/li>\n
