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) Manganese (Z = 25) | (i) Oxidation to iodate |
| (b) Ionization enthalpy | (ii) Oxidation of thiosulphate |
| (c) Silver (Z = 47) | (iii) Maximum unpaired electrons |
| (d) Potassium permanganate | (iv) Irregular variation in transition elements |
A
a-iii, b-iv, c-i, d-ii
B
a-ii, b-iv, c-iii, d-i
C
a-iii, b-ii, c-i, d-iv
D
a-i, b-iii, c-iv, d-ii
Correct Answer
Option A
Detailed Explanation
Manganese has the maximum number of unpaired electrons (iii), ionization enthalpy shows irregular variation (iv), silver can exhibit a +2 oxidation state (i), and potassium permanganate has notable reactions such as oxidation of thiosulphate (ii). These points are derived from the NCERT context provided.
