Arrange the following compounds in the order of increasing boiling points :
`(i) CH_3 CN " " (ii) CH_3 Cl " "(iii) CH_3 NC `

Explanation

To arrange the compounds CH₃CN (methyl cyanide), CH₃Cl (methyl chloride), and CH₃NC (methyl isocyanide) in the order of increasing boiling points, we need to consider their polarity and intermolecular forces.

### Step-by-Step Solution:

1. **Identify the Compounds:**
- CH₃CN: Methyl cyanide (also known as acetonitrile)
- CH₃Cl: Methyl chloride
- CH₃NC: Methyl isocyanide
