The purpose of control tests in the experiment of classification of alcohols through oxidation reactions is to ensure the accuracy and reliability of the results obtained. Control tests are used to verify that the experimental conditions are consistent and that any observed differences in reactivity between primary, secondary, and tertiary alcohols are due to the structural differences in the alcohols themselves, rather than any other factors.
Specifically, control tests may include:
1. Testing a known primary alcohol as a reference to confirm that the oxidation reaction proceeds as expected for a primary alcohol.
2. Testing a known secondary alcohol as a reference to confirm that the oxidation reaction proceeds as expected for a secondary alcohol.
3. Testing a known tertiary alcohol as a reference to confirm that the oxidation reaction proceeds as expected for a tertiary alcohol.
4. Performing blank tests with no alcohol present to ensure that any observed color changes or other reactions are not due to impurities in the reagents or other sources of error.
By including control tests in the experiment, researchers can ensure that the results are valid and that any conclusions drawn about the reactivity of primary, secondary, and tertiary alcohols are based on sound experimental evidence.

The purpose of a control test in the experiment for classifying alcohols (primary, secondary, or tertiary) through oxidation reactions is to:
- Validate the accuracy of the oxidation reaction: By performing the control test without the unknown alcohol, the experimenter can verify if the oxidation reaction is working correctly and giving the expected results. This helps to eliminate false positives or negatives in the classification of the unknown alcohol.
- Rule out interferences: Any unexpected results or reactions observed in the control test can help identify potential interferences or impurities in the reagents or glassware used in the experiment. This allows the experimenter to take appropriate measures to minimize or eliminate these interferences before testing the unknown alcohol.
- Determine the specificity of the oxidation reaction: The control test helps assess if the oxidation reaction is specific for the classification of alcohols or if it reacts with other functional groups or compounds. This information ensures that the classification results obtained for the unknown alcohol are reliable and accurate.
- Provide a baseline for comparison: The results obtained from the control test serve as a reference point for comparing the results of the unknown alcohol. This helps in interpreting the observations and making more accurate deductions about the classification of the unknown alcohol.
- Quality control: Including a control test as part of the experimental procedure demonstrates good laboratory practices and helps maintain the integrity and reliability of the results. It ensures consistency and reproducibility in the classification of alcohols and allows for troubleshooting if unexpected results are encountered.
