NEET Chemistry Oxidation Number Match the Following Question
Type: Match the Following-match the column-Medium-Class 11
Match Column-I with Column-II.
| Column-I | Column-II |
|---|---|
| (a) Chromium in Cr2O7^2– | (i) +6 oxidation state |
| (b) Sulphur in SO3^2– | (ii) +4 oxidation state |
| (c) Chromium in Cr^3+ | (iii) +3 oxidation state |
| (d) Sulphur in SO4^2– | (iv) +6 oxidation state |
A
a-i, b-ii, c-iii, d-iv
B
a-ii, b-i, c-iv, d-iii
C
a-i, b-iv, c-ii, d-iii
D
a-iii, b-ii, c-i, d-iv
Correct Answer
Option A
Detailed Explanation
In the dichromate ion (Cr2O7^2–), chromium has an oxidation state of +6, while in the sulphite ion (SO3^2–), sulphur has an oxidation state of +4. In Cr^3+, chromium's oxidation state is +3, and in the sulphate ion (SO4^2–), sulphur is +6. These are all consistent with the provided NCERT context.
