for tautomerism to occur , atleast one alpha hydrogen must be acidic??
what alpha hydrogen & acidic hydrogen means here & how multiple bond on cyclocompounds reduce acidic character of hydrogen???plzzz..explain.
acidic hydrogen means which attach with more electrondonating group. always remember that sp hybridized carban attach hydrogen is more acidic . in tauto merism atlist one alpha H atom is required for come out to hydrogen and become enol content.alpha H means attach alpha carben atom . if it is acidic or not always remove alpha H. mostly alpha H is acidic in tautomerism,
