Match List I with List II.
| List I | | List II | |---|---|---| | A. van't Hoff factor, i | | I. Cryoscopic constant | | B. | | II. Isotonic solutions | | C. Solutions with same osmotic pressure | | III. | | 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
A-III, B-I, C-II, D-IV
Strategy:\n> Match core colligative property definitions and solution behaviors with their standard terminology and formulas.\n\nMatching Breakdown:\n- A. van't Hoff factor (i): A measure of dissociation or association, defined as the ratio of observed (abnormal) properties to calculated (normal) ones, but for molar mass, it is . III\n- B. : Also known as the Cryosco\pic constant, it describes the depression of freezing point per 1 molal concentration. I\n- C. Isotonic solutions: These are solutions having the same osmotic pressure. II\n- D. Azeotropes: Constant boiling mixtures where the liquid and vapour phases have the same composition. IV\n\nConclusion: A-III, B-I, C-II, D-IV.\n\n
