NEET Chemistry Properties of d-block Match the Following Question
Type: Match the Following-match the column-Medium-Class 12
Match Column-I with Column-II.
| Column-I | Column-II |
|---|---|
| (a) Manganese(II) oxidation state | (i) Exhibits +2 to +7 states |
| (b) Scandium(II) oxidation state | (ii) Virtually unknown |
| (c) Zinc oxidation state | (iii) Only +2 state |
| (d) Titanium(IV) oxidation state | (iv) More stable than Ti(III) |
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-ii, d-i
Correct Answer
Option A
Detailed Explanation
Manganese can exhibit oxidation states from +2 to +7, making option A the correct pairing. Scandium(II) is indeed virtually unknown, zinc only displays the +2 oxidation state, and titanium(IV) is more stable than its lower oxidation states.
