Starting from materials having five or fewer carbons how 3-methyl-2-hexenoic acid (mixture of E and Z isomers) can be synthesized is to be shown. Concept introduction: The following steps are involved in the synthesis of 3-methyl-2-hexenoic acid (mixture of E and Z isomers) from materials having five carbons i) Nucleophilic addition of a Grignard reagent (with an unsaturated carbon chain) to the carbonyl carbon in a methyl ketone to get an unsaturated alcohol ii) Addition of water to the double bond through hydroboration followed by oxidation to yield a diol . iii) Oxidation of the alcohol to acid iv) dehydration of the acid to get the unsaturated acid. To show: Starting from materials having five or fewer carbons how 3-methyl-2-hexenoic acid (mixture of E and Z isomers) can be synthesized.

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
