Vedclass · Answer

(C) Propionaldehyde $(CH_3CH_2CHO)$ contains $\alpha$-hydrogens and undergoes an aldol condensation reaction in the presence of dilute $NaOH$. The reaction involves the formation of an enolate ion from one molecule of propionaldehyde,which then attacks the carbonyl carbon of another molecule. The product formed is $3$-hydroxy-$2$-methylpentanal,which is represented as $CH_3CH_2CH(OH)CH(CH_3)CHO$.
