Carbonic Acid and Alcohol
« on: December 23, 2009, 04:30:25 AM »
Do you know why Carbonic Acids Dissociate, but Alcohol not ?
I think that it's because Carbonic Acid are better polarised than Alcohol.
Am I right ?

And why only H+ ion dissociate not OH- in acids ?

The usual answer we tell students is that the negative charge from the disassociated product is stabilized by the carboxylate group through resonance. An alcohol does not have resonance stabilization.

Most Common Suggestions I Make on the Forums.
1. Start by writing a balanced chemical equation.
2. Don't confuse thermodynamic stability with chemical reactivity.
3. Forum Supports LaTex

Resonance stabilisation is why phenol behaves differently to say benzyl alcohol.
