उत्तर
[Mn(CN)6]3-
Mn = [Ar]3d54s2
Mn3+ = [Ar]3d4
Mn (ground state)
Mn in +3 state
Mn in [Mn(CN)6]3-
d2sp3 hybridisation
xx are electrons donated by ligand CN-
Type of hybridization – d2sp3

During chemistry class, a teacher wrote \[\ce{[Ni(CN)4]^2-}\] as a coordination complex ion on the board. The students were asked to find out the magnetic behaviour and shape of the complex. Pari, a student, wrote the answer paramagnetic and tetrahedral whereas another student Suhail wrote diamagnetic and square planer.
Evaluate Pari’s and Suhail’s responses.
