(b)
Interpretation: The reagents that are used to make the given compound of aldol condensation have to be found.
Concept Introduction:
Retro synthetic analysis:
It is the analysis of the synthetic starting materials for a given compound through its precursors or fragments which are known as synthons. The synthons can be obtained by logical cleavage of the chemical bonds in the compounds. The resulted synthons will be therefore known as logical synthons.
Crossed aldol condensation:
Crossed aldol condensation reaction occurs, when an aldehyde and a ketone are heated in aqueous sodium hydroxide. The resulted product will be an
