The structure of valine is to be stated. The rotation of valine that is prepared by halogenation of 3- methylbutanoic acid is to be identified. Concept Introduction: > The carboxylic acids that contain α- hydrogen atoms in their structure on reaction with halogen in the presence of phosphorous trichloride ( PCl 3 ) results in the formation of α- halo carboxylic acids as the final products. Such a reaction is called as Hell-Volhard-Zelinsky reaction. > A mixture that has equal amount of enantiomers is commonly known as racemic mixture. Enantiomers have non-superimposable mirror images of one another and therefore; they rotate the plane of polarized light in opposite but equal direction. The racemic mixture is optically inactive in nature.

Answer 1

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.
