Question

The van’t Hoff factor i for an electrolyte which undergoes dissociation and association in solvents are respectively:

• A. greater than 1 and greater than 1
• B. less than 1 and greater than 1
• C. less than 1 and less than 1
• D. greater than 1 and less than 1

Hint:

The van’t Hoff factor is greater than 1 for dissociation and less than 1 for association.

Answer 1

The Correct Option is D

Step 1: van’t Hoff factor.
The van’t Hoff factor \( i \) is greater than 1 for electrolytes that dissociate, as it represents the number of ions produced. If association occurs, the factor is less than 1 as fewer ions are formed.
Thus, the correct answer is (4).
