Arrange the following in the increasing order of boiling points:
(i) Acetaldehyde (ii) Acetic acid
(iii) Ethyl alcohol (iv) `CH_(3)OCH_(3)` (v) `CH_(3)CH_(2)CH_(3)`

Explanation

To arrange the compounds in the increasing order of boiling points, we need to consider the types of intermolecular forces present in each compound. The boiling point of a substance is influenced by the strength of these forces. Here’s a step-by-step breakdown of the process:

### Step 1: Identify the Compounds and Their Structures
1. **Acetaldehyde (CH₃CHO)** - An aldehyde.
2. **Acetic acid (CH₃COOH)** - A carboxylic acid.
3. **Ethyl alcohol (C₂H₅OH)** - An alcohol.
4. **Dimethyl ether (CH₃OCH₃)** - An ether.
5. **Propane (C₃H₈)** - An alkane.
