Q.
Maximum enol content is observed in
Organic Chemistry – Some Basic Principles and Techniques
Solution:
In $1,3$ -diketones, the enol content is high due to stabilization of the enol both by $H-$ bonding and resonance. Further since the $C = O$ group in ketones is a much stronger electron withdrawing group than in esters, therefore, the enol content is much higher $(76 \%)$ in acetylacetone than in ethyl acetoacetate $(8 \%)$
