What is an advantage of using gas chromatography in organic chemistry?

• A. It is less time-consuming than liquid chromatography
• B. It can separate volatile compounds quickly and efficiently
• C. It does not require solvents
• D. It provides real-time analysis

Answer: (B)

Gas chromatography (GC) is particularly advantageous in organic chemistry due to its ability to separate volatile compounds quickly and efficiently. This method utilizes a gas as the mobile phase, allowing for rapid analysis of gases and small organic molecules that can vaporize without decomposing. The high efficiency of separation is achieved through a stationary phase that interacts with the components of the sample, making it suitable for complex mixtures. The quick analysis time is particularly beneficial in many practical applications, such as environmental monitoring, food and flavor analysis, and pharmaceutical quality control, where it is vital to obtain accurate results in a short period. Moreover, GC often provides high resolution and sensitivity, further enhancing its utility in analytical applications. While it is true that gas chromatography can be less time-consuming than other methods and can sometimes operate without solvents, the key strength lies in its effectiveness in dealing with volatile substances, which is crucial for many organic compounds. Additionally, it can provide real-time analysis in some configurations, but this aspect is not as widely recognized as the efficiency and speed of separation it offers for volatile compounds.
