Purification of Organic Compound
Question 1: What is the basic principle of chromatography?
Answer:
Chromatography is based on the idea of separating molecules in a mixture that has been added to the ground or solid and liquid stationary states (stable phase) while travelling with the help of a mobile phase.
Question 2: What is the Rf value in chromatography?
Answer:
In paper chromatography, RF refers to the distance a fluid component goes up a chromatography plate. All chemicals have a common RF value for each solvent, and RF values are used to match unknown samples with known compounds.
Question 3: What are the four major purifying methods?
Answer:
Four major purifying methods are as follows:
- Filtering
- Crystalline Formation
- Sublimation
- Distillation
Question 4: How can sublimation be used to purify organic compounds?
Answer:
Sublimation is the process of transforming a solid into a gas without passing through the liquid state. This technique can be used to purify compounds that are sublimable or have vapor pressures that reach atmospheric pressure well before they reach their melting temperatures.
Purification of Organic Compounds
Organic chemistry is the study of carbon-containing molecules’ structure, characteristics, content, reactions, and production. The majority of organic compounds contain carbon and hydrogen, but they may also contain a variety of other elements (e.g., nitrogen, oxygen, halogens, phosphorus, silicon, and sulfur).
Organic chemistry was originally limited to the study of molecules created by living organisms, but it has now expanded to encompass man-made substances.
