tetrahedral and square planar

B

both tetrahedral

C

square planar and tetrahedral

D

both square planar

Text Solution

Verified by Experts

The correct Answer is:
A
`{:([X] to K_(2)[Ni(CN)_(4)],, B to K_(2)[overset(+2)(Ni)(DMG)_(2)]) , ("(Tetrahedral)" , "(Square planar)"), ("(spin free)" , "(spin paired)"), (d^(7) "," sp^(3), d^(8) "," dsp^(2)), (3u.p . e^(-)"(Paramag.)" , "(Dimag.)"):}`
