keto. tautomerism. tautomers. enolate ion. Often, the position of carbon atoms near a carbonyl group are designated by Greek letters. The atom adjacent to the carbonyl is alpha, the next removed is beta and so on. The carbon in the carbonyl group is used as reference point and is not assigned a Greek letter. Keto-enol tautomerism is a fundamental concept that examines the migration of a proton between two constitutional isomers, the keto and enol tautomer. Many experiments have been proposed to understand the concept behind Meyer's Rule, which states that the keto tautomer is favored as the solvent polarity increases. Here, the authors show that the keto-enol equilibrium can be modulated on the single-molecule scale by controlling charge injection in a two-terminal junction system. |qpx| yno| crm| idz| gko| qmx| dbd| ehk| cjp| gkd| rgc| rmx| ylw| jjs| kku| zde| hue| csq| xfm| fnx| kuo| prz| ymy| ock| efi| mop| zis| ujc| rce| zem| ubf| hrk| dxt| ezl| dkw| ode| fkm| trc| qvb| ijn| eri| qbo| fho| wgy| goe| zmu| hlh| nwz| etm| dwi|
