Q1

The following solutions were prepared by dissolving \( 10 \mathrm{~g} \) of glucose \( \left(\mathrm{C}_{6} \mathrm{H}_{12} \mathrm{O}_{6}\right) \) in \( 250 \mathrm{~ml} \) of water \( \left(\mathrm{P}_{1}\right), 10 \mathrm{~g} \) of urea \( \left(\mathrm{CH}_{4}\mathrm{~N}_{2} \mathrm{O}\right) \) in \( 250 \mathrm{~ml} \) of water \( \left(\mathrm{P}_{2}\right) \) and \( 10 \mathrm{~g} \) of sucrose \( \left(\mathrm{C}_{12} \mathrm{H}_{22} \mathrm{O}_{11}\right) \) in \( 250 \mathrm{~ml} \) of water \( \left(\mathrm{P}_{3}\right) \). The right option for the decreasing order of osmotic pressure of these solutions is

[NEET 2021]

a

\( \mathrm{P}_{1}>\mathrm{P}_{2}>\mathrm{P}_{3} \)

b

\( \mathrm{P}_{2}>\mathrm{P}_{3}>\mathrm{P}_{1} \)

c

\( \mathrm{P}_{3}>\mathrm{P}_{1}>\mathrm{P}_{2} \)

d

\( \mathrm{P}_{2}>\mathrm{P}_{1}>\mathrm{P}_{3} \)
