I know pKa has to do with dissociation of an acid into ions, so my instinct would be to say that nonionizable compounds don't have a pKa, but is it even possible for something to NOT have a pKa?

And it's impossible to make a salt of a nonionizable compound, right?


Thanks for any *delete me*

I suppose what this comes down to, is what is meant by a "non-ionisable compound". Sure, butane isn't likely to exist as an ion pair, but you can draw resonance forms etc that show it as such, and they all contribute something (not a lot, perhaps), to the structure.
