This is a two stage reaction.
Proton transfer occurs in a slow, rate determining step.
Acetic acid is a weaker acid.
The protonated substrate reacts further to give the product(s) in the (slow) rate determining step.
Most ketones are almost 100% in the enol form.
True
False
Acid-base catalysis often involves proton transfer.
True

The structure of the compounds below after the movement of an a hydrogen and the shifting of bonding electrons in keto-enol tautomerism is
In acid catalyzed ester hydrolysis, the acid catalyze two slow steps.
True
False
Rate of proton transfer to N, O and S is slow hence it is diffusion-controlled.
