Arrange the following solutions as:
Increasing order of boiling points-
`0.001 m NaCl` , 0.001 m urea
`0.001 m MgCl_(2)` , `0.001 m CH_(3)COOH`

Explanation

To arrange the given solutions in increasing order of boiling points, we need to consider the van't Hoff factor (i) for each solute, which accounts for the number of particles the solute dissociates into when dissolved in a solution. The boiling point elevation can be calculated using the formula:

\[ \Delta T_b = i \cdot K_b \cdot m \]

Where:
- \( \Delta T_b \) is the boiling point elevation,
