(a)

Interpretation Introduction

Interpretation:

The aldol condensation product for the given molecule should be identified.

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)

Please note that aldol condensation product is formed at higher temperature.

Note: Simple way to enter aldol condensation product is to remove the two α hydrogens from one carbonyl molecule and oxygen from another carbonyl molecule.  Form a double bond between the carbon atoms as shown in scheme below,
