The enolate that is formed when the given ketone reacts with LDA has to be drawn. Concept Introduction: The structure of LDA : The name L D A stands for L i t h i u m d i i s o p r o p y l a m i d e . Since LDA is being a bulky base, it always prefers to attack only the less hindered site α- Carbon atom of ketone and forms the enolate which will be resonance stabilized. Enolate formation: When ketones are treated with a strong base, the α-position of the ketone will be deprotonated to give a resonance-stabilized intermediate called an enolate . Example:

Question

Definition Definition Organic compounds that have a carbonyl group, C = O, as their functional group. The carbonyl group in ketones is placed somewhere in the middle of the molecular structure, which means, the C=O is attached to two alkyl groups or benzene rings. Just like all other homologous series, the naming of ketones is done using a common suffix “-one”. The general molecular formula is C n H 2n O. Functional group of a ketone
