### Gas Chromatography (GC) Analysis of Borneol and Isoborneol

#### Overview of the GC Graph
The displayed graph is a Gas Chromatography (GC) output for a mixture containing acetone, isoborneol, and borneol. The x-axis represents the retention time in minutes, while the y-axis represents the detector response, or counts, which correlates to the abundance of a substance eluting from the chromatography column.

- **Peak at 0.82 min**: This peak, with the highest intensity, corresponds to acetone.
- **Peak at 2.14 min**: This peak corresponds to isoborneol.
- **Peak at 2.45 min**: This peak corresponds to borneol.

#### Tabulated Data for Components
| Component | Peak Area | Boiling Point (°C) |
|-----------|-----------|---------------------|
| Acetone   | 8.06E+04  | 56                  |
| Isoborneol| 4.84E+04  | 210                 |
| Borneol   | 1.61E+04  | 213                 |

#### Analysis Question
**Which of the isomers, isoborneol or borneol, has the highest concentration in the mixture, and why?**

Choices:
1. o Isoborneol; because it comes out first
2. o Borneol; because it comes out first
3. o Borneol; because it has the largest peak area
4. o Isoborneol; because it has the largest peak area

#### Answer Analysis
To determine which isomer has the highest concentration, we examine the peak areas of isoborneol and borneol. The concentration of a compound in the mixture is directly proportional to the peak area in the GC output.

- **Isoborneol Peak Area**: 4.84E+04
- **Borneol Peak Area**: 1.61E+04

Since isoborneol has a larger peak area compared to borneol, it indicates that isoborneol is present in higher concentration within the mixture.

Therefore, the correct answer is:
**Isoborneol; because it has the largest peak area.**

**Question 7 [Redacted]**

Borneol and isoborneol were formed in a reaction. Use the following GC chromatogram of the isoborneol and borneol dissolved in acetone to answer the question: **Please note that the question is below the chromatogram.**

![Graph Description]
The provided graph is a Gas Chromatography (GC) chromatogram of borneol and isoborneol dissolved in acetone. The x-axis represents time in minutes, while the y-axis represents counts (indicative of the amount of substance detected). 

There are three peaks in the chromatogram:
1. The first peak appears at approximately 0.82 minutes.
2. The second peak appears at approximately 2.14 minutes.
3. The third peak appears at approximately 2.45 minutes.

Below the chromatogram, a table lists the components, their corresponding peak areas, and boiling points:

| Component | Peak Area | Boiling Point (deg. C) |
|-----------|-----------|------------------------|
| Acetone   | 8.06E+04  | 56                     |
| Isoborneol| 4.84E+04  | 210                    |
| Borneol   | 1.61E+04  | 213                    |

**Question:**
Which of the isomers, isoborneol or borneol, has the highest concentration in the mixture and why?

**Answer:** 
Isoborneol has the highest concentration in the mixture. This conclusion is derived from examining the peak areas in the GC chromatogram. The peak area for isoborneol is 4.84E+04, whereas the peak area for borneol is 1.61E+04. Since the peak area is directly proportional to the concentration of the component in the mixture, isoborneol's higher peak area indicates a higher concentration compared to borneol.
