't Hoff factor be greater than 1?

A) NaCl in water
B) Sucrose in water
C) Ethanol in water
D) NH3 in water

Answer: A) NaCl in water

Explanation: The Van't Hoff factor (i) is a measure of the number of particles that a solute dissociates into when it is dissolved in a solvent. NaCl dissociates into two ions (Na+ and Cl-) when it is dissolved in water, so the Van't Hoff factor for NaCl in water is 2. Sucrose, ethanol, and NH3 do not dissociate into ions when they are dissolved in water, so their Van't Hoff factor is 1. Therefore, option A is the correct answer.

In which of the following solutions will the Van’t Hoff Factor f...
The Van’t Hoff factor is less than 1 for solutes that dissociate in solution. In the given list, only sodium chloride dissociates in water whereas the remaining carboxylic acids associate in benzene. Hence, the value of the Van’t Hoff factor is lesser than 1 for a solution of sodium chloride in water.
