on the trends of acidity, the reason that the more electronegative atoms
will have a greater tendancy to lose protons is because they are more
negative, and so their protons are more positive, and so the proton is
held less tightly. i'm not sure that this helps at all, but i just try and
think of it as a study in contrasts, with the more negative atoms wanting
to lose the really positive protons.
i hope this helps (and i also hope that it is right!)
