Physical constants serve as crucial indicators for identifying organic compounds and assessing their purity, with their precise determination constituting a fundamental aspect of organic chemistry experimental education. This paper comprehensively examines the significance, underlying principles, standard methodologies, operational protocols, and experimental considerations associated with the determination of key physical constants, including melting point, boiling point, refractive index, and specific rotation. Additionally, it provides an overview of contemporary instrumental techniques employed in these measurements. The authors aim to offer valuable insights and practical guidance for chemistry educators and researchers engaged in experimental teaching and scientific investigation.
