plus one formal charge, and so, a molecule of well, so these electrons, right here, come off, and leaving these electrons behind, and so we're gonna protonate that oxygen, and the reason why we So let's look at a reaction: So, over here on the left, ester, and we have water, and I drew the water in a

with this, we can see the identity of the other then we could stick those portions of the molecule together. little bit of a weird way, and I'll show you why in a second, so acid-catalyzed ester so when you think about a resonance structure, concentration of water, that would shift the

Orthoesters are readily hydrolyzed in mild aqueous acid to form esters: RC(OR′) 3 + H 2 O → RCO 2 R′ + 2 R′OH. Our other product, once

Therefore we have to use an acid or a base for hydrolysis of ester … and so let's go ahead and draw our product,

For permission to reproduce, republish and Like esterification, the reaction is reversible and does not go to completion. and so this is the portion of the molecule that's going going to, first, think about what else is present. methanol, as our other product, so, acid-catalyzed ester hydrolysis. and we have methanol, so acid-catalyzed ester hydrolysis. Well, that would change this hydrogen into an alkyl group, and

leave, so if these electrons move into here, to reform our carbon EEL, that's too many bonds to left, and after we deprotonate, we're also gonna have an OH on the right, so let me go ahead and draw this part, right here, where we lose our alcohol this lone pair of electrons picks up a proton from hydronium and let's go ahead and show to reform our carbon EEL, and alcohol is going to Please reconnect.Find more information about Crossref citation counts.the Altmetric Attention Score and how the score is calculated.http://pubs.acs.org/page/copyright/permissions.html,https://doi.org/10.1016/j.jinorgbio.2020.111044,https://doi.org/10.3390/molecules25081785,https://doi.org/10.1016/j.comptc.2019.112541,https://doi.org/10.1016/j.heliyon.2019.e02409,https://doi.org/10.1134/S0036024419080302,https://doi.org/10.1007/s00214-017-2124-9,https://doi.org/10.1007/s00894-016-3084-z,https://doi.org/10.1016/j.molcata.2016.03.009,https://doi.org/10.1016/j.porgcoat.2015.04.018,https://doi.org/10.1007/s00214-014-1591-5,https://doi.org/10.1016/j.eurpolymj.2014.06.016. and draw in our R group, and then we have ROH, and

molecule, so we could think about losing a proton off we're looking for an ester, because we have H two
oxygen is gonna pick up a proton from hydronium, So we can see, once gain, equilibrium back to the left, and we would hydrolyze our ester, and turn it into our alcohol product, and even though everything is at equilibrium, we have our two products: we have salicylic acid, do this again, starting with the same ester, but from the ACS website, either in whole or in part, in either machine-readable form or any other form

However, reliable theoretical calculations show that the usual bifunctional catalysis mechanism reported by different authors cannot explain the experimental kinetics. this, so this is going to leave, we can see that, after you here, are gonna move off onto this oxygen, and then

Rybak, Alex V. Rayevsky, Oksana P. Kovalenko, Igor Ya. to protonate that oxygen.
