Give a chemical test to distinguish between methanol and ethanol.

Explanation

To distinguish between methanol (CH₃OH) and ethanol (C₂H₅OH), we can perform the Iodoform test. Here’s a step-by-step solution:

### Step 1: Understand the Iodoform Test
The Iodoform test is a qualitative test used to identify the presence of methyl alcohols (like ethanol) that can be oxidized to form a methyl ketone. In this case, ethanol can be oxidized to acetaldehyde, which can then react with iodine to form iodoform.

### Step 2: Prepare the Reaction
Take a small amount of ethanol and mix it with iodine (I₂) in the presence of sodium hydroxide (NaOH). The reaction can be represented as:
\[ \text{C}_2\text{H}_5\text{OH} + \text{I}_2 + \text{NaOH} \]
