Keto Enol Tautomerism - Acidic & Basic Conditions

This organic chemistry video tutorial explains the concept of the keto enol taumerism / tautomerization process. It provides the acid catalyzed reaction mechanism of ketone converting to its enol tautomer and the base catalyzed version as well. This video contains plenty of examples and practice problems of drawing the enol tautomer from the ketone. It explains the relative stability of certain enols due to conjugation of the double bond, formation of an intramolecular hydrogen bond, and the formation of aromatic ring. Examples include acetone, 2,4-pentane dione, and phenol.

    yes due to resonance (conjugation) and also due to a hydrogen bond between the keto and enol group. The keto-enol tautomer has 76% appearance. I think he made a little mistake there.

    how does the H3O+ not get consumed here i don't understand.. it is first transformed to H2O then again to H3O+, why is this not a consumption? (sorry just started my studies)

    @ihaveagoal4665

    3 жыл бұрын

    After the reaction you find the H3O+ in the same form as it was before the rxn, so even though it is used in the reaction, it isn't consumed permanently and you get is back in it's original form so basically it is used to speed up the process, and that is the definition of catalysts: they are the substance that increases the rate of a reaction without itself being consumed. we get them back in the final product. i might be wrong since i'm also a student.

    ​@@ihaveagoal4665 U are correct ! The amount of h30+ used for reaction is gotten back after the reaction so it can be cancelled out as being on reactant side of first reaction and on product side of second while practically performing experiments it always seems that the h30+(or anything else in similar situation) isn't even used and just acted as a catalyst
