Question

Match List I with List II.

List - I		List - II
A	van’t Hoff factor, i	I	Cryoscopic constant
B	$ k_f$	II	Isotonic solutions
C	Solutions with same osmotic pressure	III	$\frac{\text { Normal molar mass }}{\text { Abnormal molar mass }}$
D	Azeotropes	IV	Solutions with same composition of vapour above it

Choose the correct answer from the options given below :

• A. A-III, B-I, C-II, D-IV
• B. A-III, B-II, C-I, D-IV
• C. A-III, B-I, C-IV, D-II
• D. A-I, B-III, C-II, D-IV

Answer 1

Answer: (A)

(A) van't Hoff factor, $i$
$i =\frac{\text { Normal molar mass }}{\text { Abnormal molar mass }}$
(B) $k _{ f }=$ Cryoscopic constant
(C) Solutions with same osmotic pressure are known as isotonic solutions.
(D) Solutions with same composition of vapour over them are called Azeotrope.
