NEET 2018 Chemistry Magnetic Properties Match the Following Question
Type: Match the Following-numerical-Hard-Class 12
Match the metal ions given in column I with the spin magnetic moments of the ions given in column II and assign the CORRECT code.
| Column I | Column II |
|---|---|
| (i) Co²⁺ | (a) √8 B.M. |
| (ii) Cr³⁺ | (b) √35 B.M. |
| (iii) Fe³⁺ | (c) √3 B.M. |
| (iv) Ni²⁺ | (d) √24 B.M. |
| (e) √15 B.M. |
A
i – d, ii – e, iii – b, iv – a
B
i – a, ii – b, iii – c, iv – d
C
i – d, ii – a, iii – b, iv – c
D
i – c, ii – e, iii – a, iv – b
Correct Answer
Option C
Detailed Explanation
The spin magnetic moment is calculated using the formula √n(n+2) B.M., where n is the number of unpaired electrons. Matching is done based on this calculation.
