Web29 de ago. de 2014 · 19.2 Keto-Enol Tautomers. Alkyl hydrogen atoms bonded to a carbon atom in a a (alpha) position relative to a carbonyl group display unusual acidity. While the pK a values for alkyl C-H bonds is typically on the order of 40-50, pK a values for these alpha hydrogens is more on the order of 19-20. This can most easily be explained by … WebTautomers consist of an intimate mixture of different species of molecules (metamers or polymers) in statistical equilibrium with one another and inseparable under ordinary …

WebAnswer: Ring-chain tautomerism is most commonly seen in sugars. They exist in equilibrium between their open-chain forms and their \alpha and \beta ring forms. Carbonyl compounds in general are in equilibrium with their enol tautomers, but for most the keto tautomer is far more stable. The major... Web26 de dez. de 2024 · Correct option (b) anomers. Explanation : Glucose forms a stable hemiacetal between the -CHO group and the -OH group on the 5 th carbon. In this process, the 1 st 'C' atom becomes astrometric giving two isomers which differ in the configuration of the asymmetric carbon. These two isomers are called as anomers.
