Pick out the correct statement with respect to `[Mn(CN)_(6)]^(3-)`-

Options

A. it is `sp^(3)d^(2)`- hybridised and octahedral
B. it is `sp^(3)d^(2)-` hybridised and tetrahedral
C. it is `d^(2)sp^(3)-` hybridised and octahedral
D. it is `dsp^(2)-` hybridised and square planar.

Answer

C

Explanation

The undergo `d^(2)sp^(3)` - hybridisation, only 2 electrons are paired up and 2 electrons remain unpaired.
