Which among the following compounds will give maximum enol content in solution? asked Jul 23, 2024 in Chemistry by AaditriSharma (59.8k points) class-12; general-organic-chemistry; 0 votes. WitrynaA classic example for favoring the keto form can be seen in the equilibrium between vinyl alcohol and acetaldehyde (K = [enol]/[keto] ≈ 3 × 10 10-7). In 1,3-diketones, such as acetylacetone (2,4-pentanedione), the enol form is favored. The acid-catalyzed conversion of an enol to the keto form proceeds by proton transfer from O to carbon.

Enol form is stable when there is hydrogen bonding. It is stable when there is a carbon carbon double bond. The more substituted alkene makes the enol bond stable. Hence, CH3CHO

WitrynaThe enol forms of the given compounds are : As we can see that compound I enol form, is the most stable due to aromaticity and hydrogen bonding. Compound I I enol form is also stabilized by aromaticity, but here no hydrogen bonding is observed. Compound I I I enol form is the least stable since there is no stabilising factor like aromaticity.

Organic esters, ketones, and aldehydes with an α-hydrogen (C−H bond adjacent to the carbonyl group) often form enols. The reaction involves migration of a proton from carbon to oxygen: In the case of ketones, the conversion is called a keto-enol tautomerism, although this name is often more generally applied to all such tautomerizations. Usually the equilibrium constant is so small that the enol is undetectable spectroscopically. selling fiverr accountWitrynaWrite the order of enol contentPWIIIIII(1) I \( \) II \( \) III(2) II \( \) I \( \) III(3) III \( \) II \( \) I(4) I \( \) III \( \) II📲PW App Link ... selling fixed assets indirect methodWitryna12 lut 2016 · 1 Answer.
