AIIMS 2018 Chemistry Aldol Condensation and Diazotisation MCQ Question

Option C is correct because it accurately represents the final products of aldol condensation and diazotization reactions. In aldol condensation, two carbonyl compounds (typically aldehydes or ketones) react to form a β-hydroxy aldehyde or ketone, which can then dehydrate to yield an α,β-unsaturated carbonyl compound. The subsequent diazotization involves the conversion of an amine to a diazonium salt, which can lead to various aromatic compounds depending on the reaction conditions.

Other options may misrepresent the structural formulas or fail to show the correct functional groups involved in these reactions, such as omitting the necessary carbonyl or hydroxyl groups, leading to incorrect interpretations of the reaction pathways.
