Question

Red precipitate is obtained when ethanol solution of dimethylglyoxime is added to ammoniacal $Ni\left(II\right)$. Which of the following statements is not true?

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

Answer 1

Answer: (B)

Red complex has a tetrahedral geometry.

${Ni}^{+2}+2Dm{g}^{-}\to \left[Ni{\left(Dmg\right)}_2\right]$
