Higher the number of unpaired electrons on the central metal, higher is the spin only magnetic moment. Species Number of unpaired electron(s) [ CoF 6]3- 4 [ Fe ( CN )6]3- 1 [ Mn ( CN )6]3- 2

Species	Number of unpaired electron(s)
$[C o F_{6}]^{3 -}$	4
$[F e (CN)_{6}]^{3 -}$	1
$[M n (CN)_{6}]^{3 -}$	2

Q. Consider the following species
$(a) [C o F_{6}]^{3 -} (b) [F e (CN)_{6}]^{3 -} (c) [M n (CN)_{6}]^{3 -}$
The correct order of their spin only magnetic moment is

( a ) >( b ) > ( c )

(c) > (b) > (a)

( b ) > ( a ) > ( c )

(a) > (c) > (b)

Higher the number of unpaired electrons on the central metal, higher is the spin only magnetic moment.
