List I List II
A. van't Hoff
factor, i
I. Cryoscopic constant
B. kf II. Isotonic solutions
C. Solutions with same osmotic pressure III. Normal molar massAbnormal molar mas
D. Azeotropes IV. Solutions with same composition of vapour above it

Choose the correct answer from the options given below:

  1. A-III, B-I, C-II, D-IV
  2. A-III, B-II, C-I, D-IV
  3. A-III, B-I, C-IV, D-II
  4. A-I, B-III, C-II, D-IV

Solution

(A) van't Hoff factor, it is used in measuring colligative properties

i= Normal molar mass  Abnormal molar mass 

(B) kf= Cryoscopic constant or molal freezing constant

(C) Solutions with same osmotic pressure are known as isotonic solutions.

(D) Solutions with same composition of vapour over them are called Azeotrope or azeotrophic mixtures.
