Solution 1
Two molecules of ethanal condense in presence of a dilute NaOH to form 3 hydroxybutanal.
Solution 2
Reaction of acetaldehyde with acetaldehyde in the presence of dilute NaOH, this is the kind of Aldol reaction by which obtained 3-hydroxybutanal as product. Further proceed reaction when using heat in the reaction, its gives aldol condensation product which is But-2-enal
