Question

Match the following:

List-I (Aquated ion)	List-II (Colour)
A) Ni\(^{2+}\)	V) Green
B) Fe\(^{3+}\)	III) Yellow
C) Mn\(^{3+}\)	I) Violet
D) V\(^{4+}\)	II) Blue

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

Hint:

Transition metal ion colors in aqueous solution arise due to d–d transitions and depend on oxidation state and ligand field.

Answer 1

The Correct Option is D

Ni$^{2+}$ — green
Fe$^{3+}$ — yellow
Mn$^{3+}$ — violet
V$^{4+}$ — blue
