NEET Chemistry Properties of d-block Assertion Reason Question
Type: Assertion Reason-assertion-Hard-Class 12
Assertion (A): The first series of transition metal ions exhibit paramagnetism. | Reason (R): The magnetic moment of these ions is primarily determined by the number of unpaired electrons.
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
Both the assertion and reason are true as paramagnetism in transition metals arises from unpaired electrons, and the magnetic moment is calculated using the spin-only formula based on these unpaired electrons.
