Solution
The correct option is C CH3CH2CHO
Aldol condensation occurs in aldehydes having α-hydrogen with a dilute base to give β-hydroxy aldehydes called aldols. This reaction is most commonly known as aldol condensation. If the condensation reaction occurs between two different carbonyl compounds it is called crossed aldol condensation.
Aldol condensation can be defined as an organic reaction in which enolate ion reacts with a carbonyl compound to form β-hydroxy ketone or β-hydroxy aldehyde, followed by dehydration to give a conjugated enone.
The presence of alpha hydrogen is necessary for a compound to undergo aldol condensation reaction. Compounds (a) , (b) and (c) have atleast one α−hydrogen. So they can undergo aldol condensation . Compound (d) benzaldehyde(PhCHO) does not have any alpha hydrogen, it will not give aldol reaction with dil. NaOH.
