What is the correct sequence of osmotic pressure of 0.01 M aq. Solution of :
(1)`Al_(2)(SO_(4))_(3) " " (2) Na_(3)PO_(4)`
(3) `BaCl_(2)" "` (4) Glucose

Options

A. `pi_(4)gtpi_(2)gtpi_(3)gtpi_(1)`
B. `pi_(3)gtpi_(4)gtpi_(2)gtpi_(1)`
C. `pi_(3)gtpi_(4)gtpi_(1)gtpi_(2)`
D. `pi_(1)gtpi_(2)gtpi_(3)gtpi_(4)`

Explanation

`pi=iCRT, i=5` for `Al_(2)(SO_(4))_(3)`,
`i=4` for `Na_(3)PO_(4)`
`i=3` for `BaCl_(2), i=1` for glucose
So osmotic pressure of :
Glucose `lt BaCl_(2) lt Na_(3)PO_(4) lt Al_(2) (SO_(4))_(3)`
