Hi! i read through your notes for keto-enol-tautomerism. I just have a questions, why is 2,4-pentandione is more favourable as an enol? is it because of the conjugation? could you please explain to me why? Thank you.



Two reasons! 1) if one ketone is present as an enol, then it can participate in a hydrogen bond with the other ketone carbonyl, which is a favorable interaction. And yes 2) it is also conjugated, so that has an impact as well.



which conditions are suitable for amide tautomerism …………..for proton abstraction

Thanks, I need to fix this.
