Draw all the enol tautomers for each of the ketones in 1.

Solution:

Here we have to write the enol tautomers for each of the given ketones

Keto-enol tautomerism:- keto-enol tautomerism represents the  chemical equilibrium between a keto form (a ketone or an aldehyde) and an enol (an alcohol). Tautomers are two molecule, one have enol and other has keto forms. This reaction involves intermolecular transfer of proton from the active Carbon of the carbonyl compound to the O-atom of the carbonyl function.

The given ketones are

,and

(propan-2-one)                (hexan-3one)                                           (2-cyclohexylethan-2-one)

Step 1

Keto-enol tautomerism of propan-2-one has been carried out as follows,

(propan-2-one)                            (enol-form)
