MCQ
Which of the following aqueous solution will exhibit highest boiling point
- A$0.01\, M$ $Na_2SO_4$
- B$0.01\, M$ $KNO_3$
- ✓$0.015\, M$ urea
- D$0.015\, M$ glucose
✓
Answer
Correct option: C.
$0.015\, M$ urea
c
$\Delta T_{f}=$ Molality $\times K_{f} \times i$
$\Delta T_{f}=$ Molality $\times K_{f} \times i$
$\Longrightarrow 3.72=1 \times 1.86 \times i$
$\Longrightarrow i=2,$ hence complex is binary.
Also, $C N$ of $P t$ is $6$ and complex is hydrated.
so complex is $\left[ Pt \left( H _{2} O \right)_{3} Cl _{3}\right] Cl \cdot 3 H _{2} O$
