Match Column-I with Column-II.
Column-I Column-II (a) Cr in Cr2O72– (i) +6 (b) S in SO32– (ii) +4 (c) Cr in Cr3+ (iii) +3 (d) S in SO42– (iv) +6
Choose the correct matching:
a-i, b-ii, c-iii, d-iv
a-ii, b-i, c-iv, d-iii
a-i, b-iv, c-iii, d-ii
a-iv, b-iii, c-i, d-ii
Correct Answer
Detailed Explanation
Chromium in Cr2O72– has an oxidation number of +6, sulfur in SO32– has +4, chromium in Cr3+ has +3, and sulfur in SO42– has +6, as indicated in the provided NCERT context.
