Chemistry-Oxidation Number
NEET Chemistry Oxidation Number Match the Following Question
Type: Match the Following-match the column-Hard-Class 11
Match Column-I with Column-II.
| Column-I | Column-II |
|---|---|
| (a) Oxidation number of carbon in CO3^{2-} | (i) +4 |
| (b) Oxidation number of sulfur in SO2 | (ii) +6 |
| (c) Oxidation number of chromium in Cr2O7^{2-} | (iii) +2 |
| (d) Oxidation number of iron in FeCl2 | (iv) +3 |
A
a-i, b-ii, c-iv, d-iii
B
a-ii, b-i, c-iii, d-iv
C
a-i, b-iv, c-ii, d-iii
D
a-iv, b-iii, c-i, d-ii
Correct Answer
Option C
Detailed Explanation
The oxidation number of carbon in CO is +4 (a-i), sulfur in SO2 is +4 (b-iv), chromium in Cr2O is +6 (c-ii), and iron in FeCl2 is +2 (d-iii). The correct matches are a-i, b-iv, c-ii, d-iii, reflecting the rules for calculating oxidation numbers.
