Acidity of a-hydrogen atoms enolate formation

Bases can abstract a-protons from carbonyl compounds to form enolate 

Carbonyl compounds are more acidic than, for example, alkanes because the anion can be stabilised by resonance (see Section 4.3.1). 

3-Diketones (or 3-diketones) are therefore more acidic than water (which has a pKa-value of 16), as the enolate is stabilised by resonance over both carbonyl groups.
