The number of paramagnetic complex among [FeF6]^(3-), [Fe(CN)6]^(3-) , [Co(C2O4)3]^(3-), [MnCl6]^(3-)

Question

The number of paramagnetic complex among \([FeF_6]^{3-}, [Fe(CN)_6]^{3-}, [Mn(CN)_6]^{3-}, [Co(C_2O_4)_3]^{3-}, [MnCl_6]^{3-} \ \text{and} \ [CoF_6]^{3-}\) which involved in \(d^2sp^3 \) hybridization is ______.

Answer 1

Answer is: 2  

\([FeF_6]^{3-}\)	Paramagnetic	\(sp^3d^2\)
\([Fe(CN)_6]^{3-}\)	Paramagnetic	\(d^2sp^3\)
\([Mn(CN)_6]^{3-}\)	Paramagnetic	\(d^2sp^3\)
\([Co(C_2O_4)_3]^{3-}\)	Paramagnetic	\(d^2sp^3\)
\([MnCl_6]^{3-}\)	Paramagnetic	\(sp^3d^2\)
\([CoF_6]^{3-}\)	Paramagnetic	\(sp^3d^2\)

Only  \([Fe(CN)_6]^{3-}\)  and   \([Mn(CN)_6]^{3-}\) are paramagnetic and  \(d^2sp^3\) hybridisation of metal.
