Why chromatography is considered as an important tool for analysis of organic compounds.4. Two engineers are serving as trainees in a laboratory of a pharmaceutical company. One of their tasks involves determining the identity of a vitamin they were given by using any equipment or method at their disposal. As a hint, their supervisor gave them a list of possible candidates for the vitamins identity which includes: Vitamin Molecular Formula Folinic Acid C20 H23 N707 C3H11NO3 C,H,N20 C17H20N406 Pyridoxine Niacinamide Riboflavin To identify the vitamins identity, the two trainees separated their sample into two equal portions and performed two separate tests: [a.] Engr. Mayo used the flame atomic absorption spectrophotometer in order to identify the elemental composition of the sample which happens to be 59.0% C, 5.0% H and 22.9% N by mass [b.] Engr. Busog on the other hand mixed his 3.88 g sample with 30.0 mL of nitrobenzene, C,H5NO2 (Latent Heat of Fusion = 79.81 J/g). Using Beckmann's method, he determined the freezing point depression to be 7.1 deg C. Based on the tests…
