Select the incorrect property for `Fe_(4)[Fe(CN)_(6)]_(3)` complex

Options

A. `d^(2)sp^(3)` Hybridisation of coordinated Fe atom
B. Blue colour due to ligend to metal charge transfer
C. Six electrons are present in `t_(2g)` orbital
D. Less bond length of `(C-N)` than in `Fe[Fe(CN)_(6)]`

Answer

C

Explanation

`10.2=W+KE_("max"),1`
`10.2Z^(2)=w+KE_("max")2`
`lambda_(DB)=(h)/(p)=(h)/(sqrt(2m(K in))),(lambda_(1))/(lambda_(2))=sqrt((Kin_(2))/(K_(in_(1))))=2.3`
`KE_(2)=5.25KE_(1)`
`10.2z^(2)=3xx 13.6,z=2 " "&" " w=3eV`
