摘要：Extrapolation of a simple straight-line graph is used to calculate the pKaH of two cations (CH2N5+) and (HN6+) (eqn. 1 and 2) of two hypothetical molecules pentazine (CHN5) and hexazine (N6). This is achieved by simply an extrapolation of the locus of the plot of pKaH of protonated pyridine, pyridazines, s-triazine and 1,2,4,5-tetrazine versus the number of nitrogen atoms of the cyclic azines. Even well matched pKaH values for these two species were found from the extrapolation of the locus of the plot of pKaH versus average ionization potential (Iv/eV) of the neutral azines. This article is useful in graduate research classroom to explain the acid-base properties and to determine the pKaH values.
