In considering basicity (particularly of amines), often I find included with the compound a pKa. I understand that the higher the pKa of the conjugate acid, the stronger the base. But when the pKa is listed below a table of bases (for instance the wikipedia page for LDA – 36), does that refer to the pKA of the compound itself (LDA) or the protonated form?

    $\begingroup$ That would be the pKa of the protonated form. $\endgroup$
