Q. In which of the following complex ion, the central metal ion is in a state of $sp^3d^2$ hybridisation ?

KCETKCET 2006Coordination Compounds

Solution:

Electronic configuration of $Co ^{2+} $ ion

$F ^{-}$ is a weak ligand. It cannot pair up electrons with $d$ -subshell and forms outer orbital octahedral complex. $\left[ Co \left( NH _{3}\right)_{6}\right]^{3+}$ ion

$\left[ Fe ( CN )_{6}\right]^{-3}$ ion

$\left[ Cr \left( NH _{3}\right)_{6}\right]^{3+} $ ion

$NH _{3}$ and $CN ^{-}$ are strong ligands. So, they form inner orbital complex.
