NEET 2026 Chemistry Magnetic Properties MCQ Question
Type: MCQ-conceptual-Medium-Class 12
The calculated 'spin-only' magnetic moment Ti²⁺ (3d²) is:
A
5.92 BM
B
3.87 BM
C
2.84 BM
D
4.90 BM
Correct Answer
Option C
Detailed Explanation
The spin-only magnetic moment is calculated using the formula μ = √n(n+2) B.M, where n is the number of unpaired electrons. For Ti²⁺, n = 2, so μ = √8 = 2.84 BM.
