Question
Differentiate phenols from alcohol.
✓
Answer
Test to differentiate alcohols and phenols:
1. Phenol react with benzene diazonium chloride to form a red orange dye, but ethanol has no reaction with it.
2. Phenol gives purple colouration with neutral feme chloride solution, alcohols do not give such coloration with $FeCl _3$.
3. Phenol reacts with NaOH to give sodium phenoxide. Ethyl alcohol does not react with NaOH
