<u>Answer:</u> The order of increasing boiling points follows:
<u>Explanation:</u>
The expression of elevation in boiling point is given as:
where,
= Elevation in boiling point
i = Van't Hoff factor
= change in boiling point
= boiling point constant
m = molality
For the given options:
- <u>Option 1:</u> 0.12 m
Value of i = 1 (for non-electrolytes)
So, molal concentration will be =
- <u>Option 2:</u> 0.02 m LiBr
Value of i = 2
So, molal concentration will be =
- <u>Option 3:</u> 0.05 m
Value of i = 3
So, molal concentration will be =
As, the molal concentration of is the highest, so its boiling point will be the highest.
Hence, the order of increasing boiling points follows:
