Q

enol under acidic conditions mechanism…

A

double bond attacks H+ which makes a carbocation on carbon with the OH attached

resonace makes double bond with + on oxygen

H2O abstracts extra H+ on oxygen

Q

enol under basic conditions mechanism…

A

OH- abstracts H+ from alcohol, makeing O-

resonance makes carbonyl, pushes alkene double bond onto carbon (carbanion)

carbanion protonates itself from H2O
