    from the jan 09 paper - can you explain to me why carboxylic acids are stronger acids than ethanol...also how does the equilibrium constant affect the equilibrium (if its 14.5 what does it mean)

    from the jan 09 paper - can you explain to me why carboxylic acids are stronger acids than ethanol...also how does the equilibrium constant affect the equilibrium (if its 14.5 what does it mean)
    Carboxylic acids/ ethanol:

    When in water an H+ ion is lost from ethanol, leaving an O- behind. This negative charge is limited to that one oxygen, therefore the H+ is attracted back to the oxygen. (re forming the ethanol). Note that because of this the equilibrium of the reaction lies well over to the left, i.e. more ethanol than ions.

    Now considering a carboxylic acid, when the H+ is lost, a COO- group is left. However this time the negative charge left on the oxygen (not the double bonded one) is distributed between BOTH oxygens in the COO-. This means the H+ is less attracted back to where it came from, and the equilibrium is less far to the left.

    Also for F334 we do not need to know anything about equilibrium constants.
