WebEthers are less water soluble than corresponding alcohols, acids or like compounds. Alcohols and acids can both donate and accept hydrogen bonds from water, and may form more hydrogen bonds ... acidic hydrogen atoms and thus do not donate protons to base over the pH range of 0-14 or under ... the oxygen atom of an alcohol can displace … WebMost acids, however, are able to hold on to their protons more tightly, so only a small fraction of the acid is dissociated. Thus hydrocyanic acid, HCN, is a weak acid in water because the proton is able to share the lone pair electrons of the cyanide ion CN – more effectively than it can with those of H 2 O, so the reaction. HCN + H 2 O → ...

It is convention to ignore the fact that a proton is heavily solvated (bound to solvent). With this simplification in mind, acid-base reactions can be viewed as the formation of adducts: * H+ + NH3 → NH4+.

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.
