Distinction between pairs of compounds
Ethanol `(CH_(3)CH_(2)OH)` and 1-Propanol `(CH_(3)CH_(2)CH_(2)OH)`

Explanation

To distinguish between ethanol (CH₃CH₂OH) and 1-propanol (CH₃CH₂CH₂OH), we can use the Iodoform test, which is a qualitative test used to identify the presence of certain functional groups in organic compounds.

### Step-by-Step Solution:

1. **Identify the Structures of the Compounds:**
- Ethanol (C₂H₅OH) has the structure CH₃CH₂OH.
- 1-Propanol (C₃H₇OH) has the structure CH₃CH₂CH₂OH.
