Which of the following compound will undergo self aldol condensation in the presence of cold dilute alkali?

1. CH2=CH—CHO
2. CH≡C—CHO
3. C6H5CHO
4. CH3CH2CHO

Correct answer: CH3CH2CHO

Solution

Self aldol condensation requires the presence of at least one α-hydrogen atom in the compound. Among the given options, only CH3CH2CHO (propanal) has α-hydrogens, making it capable of undergoing self aldol condensation.
