FAQs on Determination of Organic Compounds Ir & Uv Video Lecture - CSIR NET Crash Course for Chemical Science - CSIR NET Chemical Science

1. How is the determination of organic compounds carried out using IR and UV spectroscopy?
Ans. Infrared (IR) spectroscopy is used to identify the functional groups present in organic compounds by measuring the absorption of infrared radiation. Ultraviolet (UV) spectroscopy, on the other hand, is used to determine the presence of conjugated systems in organic compounds by measuring the absorption of ultraviolet radiation.
2. What are the key differences between IR and UV spectroscopy in the determination of organic compounds?
Ans. IR spectroscopy is used to identify functional groups based on their unique absorption bands in the infrared region, while UV spectroscopy is used to detect conjugated systems based on their absorption of ultraviolet radiation. Additionally, IR spectroscopy provides information on bond vibrations, while UV spectroscopy provides information on electronic transitions.
3. How can IR and UV spectroscopy be used together for a more comprehensive analysis of organic compounds?
Ans. By combining IR and UV spectroscopy, researchers can obtain a more complete picture of the structure and properties of organic compounds. IR spectroscopy can provide information on functional groups, while UV spectroscopy can provide information on conjugated systems, allowing for a more detailed analysis of the compound.
4. What are the limitations of using IR and UV spectroscopy for the determination of organic compounds?
Ans. One limitation of IR spectroscopy is that it may not be sensitive enough to detect small concentrations of compounds in a mixture. UV spectroscopy, on the other hand, may not be able to differentiate between compounds with similar electronic structures. Additionally, both techniques require pure samples for accurate analysis.
5. How can researchers ensure the accuracy of the results obtained from IR and UV spectroscopy in the determination of organic compounds?
Ans. Researchers can ensure the accuracy of their results by calibrating the instruments, using standard samples for comparison, and carefully preparing their samples for analysis. It is also important to consider the limitations of each technique and to use complementary methods for a more comprehensive analysis.
