Type: Assertion Reason-assertion-Easy-Class 12
Assertion (A): The geometry of [MnBr4]2– is tetrahedral.
Reason (R): The presence of five unpaired electrons in the d orbitals results in a high magnetic moment.
A
Both A and R are true and R is the correct explanation of A.
B
Both A and R are true but R is not the correct explanation of A.
C
A is true but R is false.
D
A is false.
Correct Answer
Option A
Detailed Explanation
According to the given context, [MnBr4]2– has a magnetic moment of 5.9 BM due to five unpaired electrons, indicating a tetrahedral geometry.
