NEET Chemistry Transition Elements Match the Following Question
Type: Match the Following-match the column-Easy-Class 12
Match Column-I with Column-II.
| Column-I | Column-II |
|---|---|
| (a) Cu(I) | (i) Oxidation state +2 in aqueous solution |
| (b) Zn | (ii) Not a transition element |
| (c) MnO4- | (iii) Oxidizing agent in reactions |
| (d) Sc | (iv) Oxidation state +3 in oxides |
A
a-i, b-ii, c-iii, d-iv
B
a-ii, b-i, c-iv, d-iii
C
a-iii, b-iv, c-ii, d-i
D
a-iv, b-iii, c-i, d-ii
Correct Answer
Option A
Detailed Explanation
Cu(I) is known to have an oxidation state of +1 and can oxidize to Cu(II), which corresponds to option (i). Zinc is a d-block element, but it has a filled d-orbital configuration, so it is not considered a transition element (option ii). Manganate ion (MnO4-) acts as a powerful oxidizing agent (option iii), and scandium in Sc2O3 exhibits +3 oxidation state (option iv).
