The pair of reactants which will undergo aldol condensation to produce methyl vinyl ketone is formaldehyde and acetone.
It occurs only with aldehydes but only those aldehydes which are having alpha hydrogen within them because when two different forms of aldehydes react the elimination of waters molecule occurs which needs one alpha hydrogen within it.
CH₂O + CH3COCH3 will give methyl vinyl ketone elimination of water molecule has to be done.
Therefore, the pair of reactants which will undergo aldol condensation
to produce methyl vinyl ketone are formaldehyde and acetone.
