NEETChemistryCoordination CompoundsMCQ+4 / −1
Pick out the correct statement with respect to [Mn(CN)6]3−-−.
  1. A
    It is sp3d2 hybridised and tetrahedral.
  2. B
    It is d2sp3 hybridised and octahedral.
  3. C
    It is dsp2 hybridised and square planar.
  4. D
    It is sp3d2 hybridised and octahedral.

Correct answer: B

25Mn = [Ar] 3d54s2

Mn+3 = [Ar] 3d4

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