Acidity of α-Hydrogen: Carbonyl 
α-carbon: Next to the carbonyl carbon. 
α-Hydrogen: H of alpha carbons 
Oxygen pulls electron density out of these C-H bonds so it's easier to deprotonate the 
α-carbon of aldehydes/ketones. 
How do you increase the acidity of α-Hydrogen? 
- Resonance stability provided by the conjugate base 
- Resonance can stabilize enolate intermediate, since negative charge is distributd to 
more EN oxygen atom 
- Alpha hydrogen can easily deprotonate in basic solutions...
