NEET Chemistry Van't Hoff Factor Match the Following Question
Match Column-I with Column-II.
| Column-I | Column-II |
|---|---|
| (a) KCl | (i) 0.5 |
| (b) Ethanoic acid | (ii) 2 |
| (c) NaCl | (iii) 1.85 |
| (d) MgSO4 | (iv) 1.21 |
a-ii, b-i, c-iii, d-iv
a-ii, b-iv, c-i, d-iii
a-iii, b-ii, c-iv, d-i
a-iv, b-i, c-ii, d-iii
Correct Answer
Detailed Explanation
The van't Hoff factor for KCl is close to 2 due to its dissociation into K+ and Cl- ions. Ethanoic acid, when dimerized in benzene, has a van't Hoff factor near 0.5. NaCl's van't Hoff factor is approximately 1.85, and MgSO4's is around 1.21, which confirms option A as the correct pairing.
