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