a) Interpretation: Whether the ketone obtained by the decarboxylation of the optically active Î²- keto acid will be optically active or not is to be stated. A mechanism to explain the formation of the ketone is to be proposed. Concept introduction: The decarboxylation of a Î²- keto acid takes place through the formation of a planar enol intermediate which then tautomerizes to the keto form. If the Î²- keto acid is optically active and if the chiral centre is involved in the reaction, the ketone product will be racemic and optically inactive. If the chiral centre is not involved in the reaction then the optical activity is retained in the ketone product.

Answer 1

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

aw the major substitution products you would expect for the reaction shown below. If substitution would not occur at a significant rate under these conditions, check the box underneath the drawing area instead. Be sure you use wedge and dash bonds where necessary, for example to distinguish between major products. Note for advanced students: you can assume that the reaction mixture is heated mildly, somewhat above room temperature, but strong heat or reflux is not used.
