pKas

One thing I am apparently good at:

I am a pKa machine. I basically can tell you the pKa of just about any organic molecule off the top of my head. If I don't know it, I can usually extrapolate what it is from related structures and by how well you can stabilize the conjugate base. I continually impress people by this ability and by how rarely I need a pKa table.

Usually I have a shoddy memory for rote memorization, so I have no idea how this stuck so well.
