CCc1ccc(C2=NN(c3ccc(S(N)(=O)=O)cc3)C(c3ccc(F)cc3)C2)cc1
An acid's negative base-10 logarithmic dissociation constant (pKa) follows directly from its underlying thermodynamics; the negative pKa is directly proportional to its standard Gibbs free energy change. What is the negative pKa value of this molecule?
