It is to be determined, if the product which is not capable of cis-trans isomerism, was obtained from dianion A or B shown in the reaction. Concept Introduction: Dianion can be prepared from alpha halogenated carboxylic acids by double deprotonation using strong bases such as LDA or KNH 2 in ammonia. However, the dianion formed has carbanionic character and it can potentially act as a nucleophile to create a new carbon-carbon single bond. A new carbon-carbon single bond in these reactions is formed between the carbon atom bearing the halogen atom in the given alkyl halide and the carbanion in the dianion of the given carboxylic acid . Two substituents attached on the ring can be oriented above the ring or below the ring and thus, they will exhibit cis-trans isomerism.

Question

Definition Definition Class of organic compounds that contain a carboxyl group ( - COOH ) and has a general formula R - COOH or R - CO 2 H , where R refers to the alkyl, alkenyl, aryl, or other groups. They can undergo different chemical reactions, such as acid-base reactions, esterification, and oxidation. These are essential components of living organisms, playing important roles in metabolic processes, signaling, and as pharmaceuticals.
