STANDARD Chemistry Oxidation State Match the Following Question
Match the column I with column II and mark the appropriate choice.
(A-iii), (B-i), (C-iv), (D-iii)
(A-iv), (B-ii), (C-i), (D-iii)
(A-iii), (B-iv), (C-ii), (D-i)
(A-i), (B-ii), (C-iii), (D-iv)
Correct Answer
Detailed Explanation
The oxidation state of the central atom in each complex is determined by the charges of the ligands and the overall charge of the complex. For K₃[Co(C₂O₄)₂Cl₂], Co is +3. For [Pt(C₂H₄)Cl₃]⁻, Pt is +4. For [Fe(H₂O)₅NO]SO₄, Fe is +2. For [Ni(CO)₄], Ni is 0.
