Arrange propan-1-ol, propan-2-ol and methoxyethane in the increasing order of their boiling points.

Explanation

To arrange propan-1-ol, propan-2-ol, and methoxyethane in increasing order of their boiling points, we need to consider the structural characteristics and the types of intermolecular forces present in each compound.

### Step 1: Identify the Structures
1. **Propan-1-ol (1-propanol)**: The structure is CH3-CH2-CH2-OH. This is a straight-chain alcohol.
2. **Propan-2-ol (2-propanol)**: The structure is CH3-CHOH-CH3. This is a branched alcohol.
3. **Methoxyethane (ethyl methyl ether)**: The structure is CH3-CH2-O-CH3. This is an ether.
