Chapter 21, Problem 99IP
Interpretation Introduction

Interpretation:

Plausible mechanism for the given transformation need to be drawn.

Concept introduction:

Aldol condensation reaction is where the aldol addition product undergoes dehydration to give a conjugated enone.  In organic chemistry condensation reaction means loss of small molecules.  For aldol condensation reaction to take place the starting material should have two α hydrogens in the same carbon atom.  The driving force for aldol condensation reaction is the formation of conjugated system.  The steps involved in aldol condensation reaction are,

  • Deprotonation of α carbon
  • Attach of enolate ion with the aldehyde (nucleophilic attack)
  • Protonation of the alkoxide ion to give aldol product
  • Dehydration of the aldol addition product to form conjugated enone (aldol condensation product)

If the aldol condensation reaction takes place between two carbonyl compounds it is known as intermolecular aldol condensation reaction and if the same takes place within a single molecule means it is known as intramolecular aldol condensation reaction.

Retrol-Aldol process is the one in which the intermediates formed are the same but they appear in reverse order compared to Aldol condensation process.
