Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Solution of non-electrolyte having same concentration will boil at same same temperature.
$10\, g$ of urea; $m =\frac{\frac{1}{60}}{ v }=\frac{1}{60 v }$
$3\, g$ of glucose; $m =\frac{\frac{3}{180}}{ v }=\frac{1}{60 v }$
We know
$\Delta T _{ b }= k _{ b } \times m$
$\Rightarrow \Delta T _{ b } \propto m$
Here, molarity remains unchanged
Hence, they have the same boiling point.

Solutions
A solution is a homogeneous mixture of two or more components in which the particle size is smaller than 1 nm.
For example, salt and sugar is a good illustration of a solution. A solution can be categorized into several components.
Types of Solutions:
The solutions can be classified into three types:
- Solid Solutions - In these solutions, the solvent is in a Solid-state.
- Liquid Solutions- In these solutions, the solvent is in a Liquid state.
- Gaseous Solutions - In these solutions, the solvent is in a Gaseous state.
On the basis of the amount of solute dissolved in a solvent, solutions are divided into the following types:
- Unsaturated Solution- A solution in which more solute can be dissolved without raising the temperature of the solution is known as an unsaturated solution.
- Saturated Solution- A solution in which no solute can be dissolved after reaching a certain amount of temperature is known as an unsaturated saturated solution.
- Supersaturated Solution- A solution that contains more solute than the maximum amount at a certain temperature is known as a supersaturated solution.
