" /> Bunnett–Olsen equations - CISMeF





Preferred Label : Bunnett–Olsen equations;

IUPAC definition : The equations for the relation between log 10 ( [SH ] [S] ) H 0 and log 10 [H ] H 0 for base S in aqueous mineral acid solution, where H0 is Hammett's acidity function and log 10 [H ] H 0 represents the activity function log 10 ( γ S γ H ) γ SH for the nitroaniline reference bases to build H0. \[\log _{10}(\frac{{[SH} { }{]}}{{[S]}})- \log _{10}{[H} { }{]} (Φ - 1)\ (\log _{10}{[H} { }{]} H_{0}) pK_{{SH} { }}\] \[\log _{10}(\frac{{[SH} { }{]}}{[S]}) H_{0} Φ \ (\log _{10}{[H} { }{]} H_{0}) pK_{\mathrm{SH} { }}\];
