JEE Main Chemistry question
Three of the following four reactions are due to one similar feature of carbonyl compounds, while the fourth one is different. Which one is the fourth (odd one out)?
Answer: (C)
Solution
Aldol condensation, the Knoevenagel reaction and the haloform reaction all fundamentally rely on the acidity/enolizability of an α-hydrogen next to the carbonyl group (generating a nucleophilic enolate/carbanion that then reacts
