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 CO (i) +4 (b) Oxidation number of sulfur in SO2 (ii) +6 (c) Oxidation number of chromium in Cr2O (iii) +2 (d) Oxidation number of iron in FeCl2 (iv) +3
Choose the correct matching:
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.
