An explanation corresponding to ‘the racemization of ( R ) - ( − ) -Piperitone in a solution of sodium ethoxide in ethanol’ and ‘the conversion of menthone to a mixture of menthone and isomenthone on treatment with 90 % sulfuric acid’ are to be stated. Concept introduction: The mixture that has equal number of enantiomers is commonly known as racemic mixture. The racemic mixture is optically inactive in nature. Enantiomers are non-superimposable mirror images of each other and therefore; they rotate the plane of polarized light in equal and opposite direction.

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
