the 1 hnmr1 h nmr spectrum 24 pentanedione indicates the presence enol
2 4 Pentanedione Enol Form. There are two possible enol forms, viii and x. Web the enol form is a vinylogous analogue of a carboxylic acid.
Web the enol form is a vinylogous analogue of a carboxylic acid. The positioning of the carbonyl groups allows for the formation of a stabilizing intramolecular hydrogen bond. It forms the acetylacetonate anion c5h7o− 2 (commonly abbreviated acac− ): There are two possible enol forms, viii and x. X is by far the predominant enol as it has 1) extended conjugation and 2) substitution.
