Question

Match list I with list II

| List I (Transition Metals)| | List II (Maximum Oxidation State)
---|---|---|---
A| Ti| I| 7
B| V | II| 4
C| Mn| III| 5
D| Cu| IV| 2

Choose the correct answer from the options given below:

• A. A-II, B-III, C-I, D-IV
• B. A-I, B-II, C-III, D-IV
• C. A-III, B-I, C-II, D-IV
• D. A-II, B-I, C-III, D-IV

Answer 1

Answer: (A)

A-II, B-III, C-I, D-IV

Answer 2

Outer electron configuration of Ti = $3d^24s^2$
So, the Maximum Oxidation State of Ti = +4

Outer electron configuration of V = $3d^34s^2$
So, the Maximum Oxidation State of V = +5

Outer electron configuration of Mn = $3d^54s^2$
So, Maximum Oxidation State of Mn = +7

Outer electron configuration of Cu = $3d^{10}4s^1$
So, Maximum Oxidation State of Cu = +2

So, the correct Option is (A): A-II, B-III, C-I, D-IV
