Chemistry-Transition Elements
NEET Chemistry Transition Elements Match the Following Question
Type: Match the Following-match the column-Hard-Class 12
Match Column-I with Column-II.
| Column-I | Column-II |
|---|---|
| (a) Transition metals | (i) Paramagnetism arises from unpaired electrons. |
| (b) Manganese | (ii) Exhibits oxidation states from +2 to +7. |
| (c) Zinc | (iii) Only oxidation state is +2. |
| (d) Transition elements | (iv) High catalytic activity due to multiple oxidation states. |
A
a-i, b-ii, c-iii, d-iv
B
a-ii, b-iii, c-i, d-iv
C
a-iv, b-ii, c-i, d-iii
D
a-iii, b-i, c-iv, d-ii
Correct Answer
Option A
Detailed Explanation
All pairs in option A are accurate: transition metals exhibit paramagnetism due to unpaired electrons, manganese displays oxidation states from +2 to +7, zinc only has a +2 oxidation state, and transition elements are known for their high catalytic activity owing to their multiple oxidation states.
