Hence, the correct option is (C).
Important Questions and Preparation Tips - Phenols
Question 4:
Lowering of vapour pressure is highest for
(a) 0.1 M BaCl2
(b) 0.1 M glucose
(c) 0.1 M MgSO4
(d) urea
Solution 4:
Lowering of vapour pressure is directly proportional to the Van't Hoff factor (i).
For BaCl2,i = 3 (maximum)
Thus, BaCl2 has highest value relative lowering of vapour pressure.
Hence, the correct option is (a).
