Explain the mechanism of Aldolcondensation of acetaldehyde. – InterviewSolution

1.	Explain the mechanism of Aldolcondensation of acetaldehyde.
Answer» Solution :This reaction is CATALYSED by base. The carbanion generated is nucleophilic in nature. Hence it can bring about nucleophilic attack on carbonyl group Step 1 : The carbanion is FORMED as the `ALPHA` - hydrogen atom is removed as a proton by the base. Step 2 : The carbanion attacks the carbonyl CARBON of another unionised aldehyde molecule. Step 3 : The alkoxide ION formed is protonated by water to give 'aldol'.
