Match the item given in Column-I (method used for determining colligative property) and Column-II (for the corresponding colligative property) and find the correct order. ( array |c|c|c| & Column I & Column II A. & Beckmann method & 1. Osmotic pressure B. & array l Ostwald-Walker method array & 2. Elevation in B.P C. & array l Berkeley-Hartley method array & 3. Depression in F.P. D. & Landsberger method & array l 4.
Options
- A( array llll A & B & C & D 2 & 4 & 3 & 1 array )
- B( array llll A & B & C & D 1 & 4 & 2 & 3 array )
- C( array llll A & B & C & D 2 & 3 & 4 & 1 array )
- D( array llll A & B & C & D 3 & 4 & 1 & 2 array )
Correct answer
D. ( array llll A & B & C & D 3 & 4 & 1 & 2 array )
Step-by-step solution
The correct matching between Column I and Column II are (A) Backmann method - Depression in freezing point (B) Ostwald-Walker method - RLVP (C) Barkeley-Hartley method-Osmotic pressure (D) Landsberger method - Elevation in boiling point Thus, correct answer is option (d).
