what is keto-enol form?

Answer 1

Keto-enol is the tautomeric isomerism between a ketone and an equivalent enol.

Keto would be - C - C(=O) - C -, whereas the enol form is
- C - C(OH) = C -, where one of the two carbons alpha to the carbonyl carbon has to have a hydrogen.

Answer 2

Keto-enol tautomerization is a reorganizatrion of an enol to a keto form; the keto form is lower in energy than the enol form; but their will be an equilibrium between both forms, the keto form being favored. This bond reorganization can sometimes be a favorable factor in a reaction with a small equilibruim constant if one of the products is an enol; the equilibrium between the enol form and the keto form can sometimes add enough stability to that product to drive the equilibrium of the reaction toward products. This is a common rearrangement found in glycolysis near the end of the cycle, which illustrates how this rearrangement commonly occurs.

Answer 3

In organic chemistry, keto-enol tautomerism refers to a chemical equilibrium between a keto form (a ketone or an aldehyde) and an enol

Answer 4

keto enol forms are a type of tautomerism in which keto -ketone changes into enol-alcoholdue to the presence of acidic hydrogen

Answer 5

these are the two tauto merism forms in organic chemistry. keto form is where c=o and in enol form double bond shifts 2 neighbouring carbon and carbon has c-o-h bond. u can visit wikipedia for more.
