The process whereby a hydrogen atom attached to the alpha-carbon carbonyl compound moves to the cabonyl oxygen atom is nown as enolization or keto-enol tautomerism. Isomeric carbonyll and enol structures are tautomers. Normally, the carbonyll form is favoured but structural factor market affect K_(T). Arrange the following compounds in decreasing order of k_(T) (Tautomeric constant)
