NEET Chemistry Charge on Complex Ions MCQ Question

Type: MCQ-numerical-Medium-Class 12

The charges x and y on the following ions are (i) [Co(NH₃)₆]Cl₃ (ii) [Fe(CN)₆]y⁻ (Oxidation state of Co is +3 and Fe is +2 in their respective complexes.)

A

x = +1, y = −1

B

x = −1, y = +3

C

x = −1, y = −4

D

x = −2, y = −3

Correct Answer

Option A

Detailed Explanation

For [Co(NH₃)₆]Cl₃, the charge is +3 from Co and 0 from NH₃, so x = +1. For [Fe(CN)₆]y⁻, the charge is +2 from Fe and −6 from CN, so y = −4.
