Give one chemical test to distinguish between the Ethyne and ethanol

Explanation

To distinguish between ethyne (C₂H₂) and ethanol (C₂H₅OH), we can perform two chemical tests: the bromine water test and the Tollens' reagent test. Here’s a step-by-step solution:

### Step-by-Step Solution:

1. **Bromine Water Test:**
- **Procedure:** Add a few drops of bromine water (which is brown in color) to separate test tubes containing ethyne and ethanol.
- **Observation:**
- When ethyne is added to bromine water, the brown color of the bromine water disappears, indicating a reaction has taken place. This is because ethyne undergoes an addition reaction with bromine, forming a dibromo compound.
