NEET Chemistry Magnetic Properties MCQ Question
Type: MCQ-numerical-Medium-Class 12
The calculated spin only magnetic moment of Cr²⁺ ion is
A
87 B.M.
B
90 B.M.
C
5.92 B.M.
D
84 B.M.
Correct Answer
Option B
Detailed Explanation
Cr²⁺ has 4 unpaired electrons, and the spin-only magnetic moment is calculated using the formula μ = √(n(n+2)) B.M., where n is the number of unpaired electrons.
