Question

CH3(CH2)4COONa is the sodium salt of hexanoic acid. The water solubility of this salt is :
Options
A higher than that of hexanoic acid
Correct Answer
B lower than that of hexanoic acid
C completely insoluble
D not predictable
Correct Answer

Option A is the correct answer.

Detailed Explanation

Sodium salts of carboxylic acids are ionic compounds and are much more soluble in water than the corresponding carboxylic acids. The carboxylate salt (RCOO-Na+) dissolves readily due to ion-dipole interactions with water.

Hint

Are carboxylate salts more or less water-soluble than carboxylic acids?
