NEET Chemistry (general) Match the Following Question
Type: Match the Following-match the column-Medium-Class 12
Match Column-I with Column-II.
| Column-I | Column-II |
|---|---|
| (a) Freezing point depression | (i) 1.2 mol kg –1 |
| (b) Molality of ethylene glycol | (ii) 2.2 K |
| (c) Depression constant | (iii) 273.15 K |
| (d) Freezing point of solution | (iv) 1.86 K kg mol –1 |
A
a-ii, b-i, c-iv, d-iii
B
a-i, b-ii, c-iv, d-iii
C
a-iii, b-ii, c-i, d-iv
D
a-ii, b-iv, c-iii, d-i
Correct Answer
Option A
Detailed Explanation
The freezing point depression is calculated as 2.2 K (a-ii) based on the molality of ethylene glycol being 1.2 mol kg –1 (b-i), with the depression constant being 1.86 K kg mol –1 (c-iv) and the freezing point of the solution being calculated from the initial freezing point of 273.15 K (d-iii).
