Question
Write a chemical test to distinguish between ethanol and phenol.
Solution
Alcohol is almost neutral in nature, but phenol is slightly acidic. The ways that ethanol and phenol react with neutral FeCl3 distinguish them from one another. Whereas ethanol does not react with neutral FeCl3, phenol does, resulting in a green or purple solution.
