4 / -1

Arrange the following in decreasing order of solubility in water :

A
I > II > III

B
I < II < III

C
II > III > I

D
II > I > III

Solution

Solubility ∝ 1/M.wt.

Alcohols are more soluble than ether due to H-bonding in alcohol.

Ether are less soluble than alcohol in water.
Question 2
4 / -1

Which of the following compound does not liberate CO₂ gas on reaction with NaHCO₃ ?

A
Benzoic acid

B
Picric Acid
