NEET (UG) 2025 — Question 73

Which of the following aqueous solution will exhibit highest boiling point?

Answer: C

$\Delta \mathrm{T}_{\mathrm{b}}=\mathrm{iK} \mathrm{K}_{\mathrm{b}} \mathrm{m}$

Consider $\mathrm{m} \approx \mathrm{M}$

$\mathrm{K}_{\mathrm{b}}$ same for all $\mathrm{i} \times \mathrm{M}$

(1) $1 \times 0.01=0.01$

(2) $2 \times 0.01=0.02$

(3) $3 \times 0.01=0.03$

(4) $1 \times 0.015=0.015$

$\mathrm{iM} \uparrow \Rightarrow \Delta \mathrm{T}_{\mathrm{b}} \uparrow \Rightarrow \mathrm{T}_{\mathrm{b}} \uparrow$
