Arrange each set of compounds in order of increasing boiling points.
(i) Bromomethane, Bromoform, Chloromethane, Dibromomethane.
(ii) 1-Chloropropane, Isopropyl chloride, 1-Chlorobutane.

Explanation

To arrange the given compounds in order of increasing boiling points, we need to consider the molecular masses and the effects of branching in the molecules. Here’s a step-by-step solution for each set of compounds:

### (i) Bromomethane, Bromoform, Chloromethane, Dibromomethane

1. **Identify the Compounds:**
- Bromomethane (CH3Br)
- Bromoform (CHBr3)
- Chloromethane (CH3Cl)
