Question

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

(a) It is sp³d² hybridised and tetrahedral.

(b) It is d²sp³ hybridised and ocrahedral.

(c) It is dsp² hybridised and square planar.

(d) It is sp³d² hybridised and octahedral.

Answer 1

Correct option (b) It is d²sp³ hybridised and ocrahedral.

Explanation :

[Mn(CN)₆]^3- : Let oxidation state of Mn be x.

CN^- is a strong field ligand thus, it causes pairing of electrons in 3d-orbital.

Then, [Mn(CN)]³ has d²sp³ hybridisation and has octahedral geometry.
