STANDARD Chemistry Magnetic Properties MCQ Question
Type: MCQ-conceptual-Medium
Oxygen molecule is paramagnetic in nature. What is the paramagnetic content in terms of magnetic moment (B.M.) in O₂⁻?
A
1.732
B
3
C
1.5
D
2.5
Correct Answer
Option A
Detailed Explanation
O₂⁻ has one unpaired electron. The magnetic moment μ is calculated using the formula μ = √n(n+2) B.M., where n is the number of unpaired electrons. For O₂⁻, n = 1, so μ = √3 = 1.732 B.M.
