Red precipitae is obtained when ethanol solution of dimethylglyoxime is added to ammoniacal `Ni (II)`. Which of the following statement is not true?

Options

A. Red complex has a square planar geometry
B. Complex has symmetrical H-bonding
C. Red complex has a tretrahedral geometry
D. Dimethylglyoxime functions as bidentate ligand.

Answer

C

Explanation

`Ni^(2+)+2DMG overset(NH_(4)^(+)OH^(-))(rarr) underset("Red")([Ni(DMG)_(2)])`

DMG is strong field ligand `:.` all `e^(-)` are rearranged as

Hence complex is square planar .
