Question

The highest value of the calculated spin only magnetic moment (in BM) among all the transition metal complexes is:

• A. $5.92$
• B. $3.87$
• C. $6.93$
• D. $4.90$

Answer 1

Answer: (A)

$5.92$

$\mu =\sqrt{n(n+2)}$ BM

$n=$ Number of unpaired electrons

$n=$ Maximum number of unpaired electron $=5$

$\mu =5.92BM$

$EX:M{n}^{2+}$ complex.

Hence option A is correct.
