Polarimetry and stereochemistry: the optical rotation of Vitamin C as a function of pH

A novel experiment was prepared to help chemistry educators to improve the stereochemistry curriculum of secondary school students and undergraduate students. Based on polarimetry and Vitamin C, chemistry educators are now provided with an experiment that takes into account the delocalization of ele...

Description
Summary:A novel experiment was prepared to help chemistry educators to improve the stereochemistry curriculum of secondary school students and undergraduate students. Based on polarimetry and Vitamin C, chemistry educators are now provided with an experiment that takes into account the delocalization of electrons, and the interactions with plane-polarized light in atomic bonds. Se preparó un experimento novedoso para apoyar a los educadores de la química a mejorar el currículo de estereoquímica de la educación de bachillerato y licenciatura. Se presenta un experimento basado en polarimetría y vitamina C que toma en consideración de los enlaces químicos y su deslocalización de electrones, así como las interacciones con el plano de la luz polarizada.
