Question

This is a gas chromatography chromatogram of the 50:50 mixture of the unknown compounds before distillation.

What are the retention times for each of unknown compounds?

 

**Gas Chromatography of a Mixture**

This diagram illustrates the chromatographic output of a gas chromatography (GC) analysis of a mixture.

- **X-Axis (Time in minutes):** The horizontal axis represents time, measured in minutes, with notable time markers at 1, 3, 6, and 7 minutes. This axis shows how long each component takes to travel through the chromatographic column.

- **Y-Axis (Response):** The vertical axis indicates the response of the detector, which records the presence of different components as they elute, or pass through, the detector.

- **Peaks:** 
  - The first peak is observed at approximately 3 minutes. It is characterized by a sharp rise and fall, indicating a component with a distinct and singular presence in the mixture.
  - The second peak occurs at about 6 minutes. Similar in shape to the first, it indicates another distinct component of the mixture.

Each peak corresponds to a different substance within the mixture, and the time at which each peak appears is indicative of that component's retention time in the chromatography system. The height of each peak correlates with the concentration of the substance, where a higher peak suggests a greater presence in the mixture.
