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 | ||
a. | Co3+ | i. | |
b. | Cr3+ | ii. | |
c. | Fe3+ | iii. | |
d. | Ni2+ | iv. | |
v. |
a | b | c | d |
iv | i | ii | iii |
a | b | c | d |
i | ii | iii | iv |
a | b | c | d |
iv | v | ii | i |
a | b | c | d |
iii | v | i | ii |
As we learnt that
Magnetic Moments (spin only) -
where n= number of unpaired electron.
- wherein
Number of unpaired and corresponding magnetic moments
a.
b.
c.
d.
