Key Points:
$\beta$-Keto esters (like ethyl acetoacetate) have acidic $\alpha$-hydrogens.
Compounds with $\alpha$-hydrogens adjacent to a carbonyl group can exhibit keto-enol tautomerism.
Active methylene compounds (acidic C-H) react with active metals like Na.
Enols typically give a positive FeCl$_3$ test (coloration).
Ketones (and aldehydes) react with 2,4-DNPH to form precipitates (hydrazones).
