NEET Chemistry Crystal Field Theory MCQ Question
Type: MCQ-numerical-Medium-Class 12
The spin-only magnetic moment of a complex ion is found to be 4.9 BM. Which of the following statements about the complex is correct?
A
The complex ion likely has four unpaired electrons.
B
The complex ion is square planar.
C
The complex ion exhibits octahedral d-orbital splitting.
D
The complex ion is diamagnetic with no unpaired electrons.
Correct Answer
Option A
Detailed Explanation
The magnetic moment of 4.9 BM suggests the presence of four unpaired electrons, as the magnetic moment is calculated using the formula √(n(n+2)), where n is the number of unpaired electrons.
