WebThe product in this reaction is a 3 o (tertiary) alcohol which are less acidic and are at the higher end of the alcohol pKa range (16-18). An appropriate reagent for the protonation would be one with a pKa lower than 18. So, the A-H can be anything with a pKa < 18. For example, water can be used to protonate this intermediate:

WebMost acids, however, are able to hold on to their protons more tightly, so only a small fraction of the acid is dissociated.
