Chloral has three electronegative chlorine units attached to the
α
-carbon (Cl
3
C-) to
the aldehydes. The carbonyl carbon bears a partial positive charge so such
electronegative elements destabilizes the carbonyl and favors the equilibrium
towards significant formation of the hydrate product. For acetaldehyde, on the other
hand, the equilibrium constant is 1.

certain reaction conditions even this is possible.
