Question

$ds{p}^2$ hybridisation is in :

• A. $\left[Ni\right(CN{)}_4{]}^{2-}$
• B. $\left[Pt\right(en{)}_2{]}^{2+}$
• C. both (a) and (b)
• D. None of these

Answer 1

Answer: (C)

both (a) and (b)

Ni has a charge of +2 and it forms 4 bonds. It has $ds{p}^2$ hybridisation because parent central ion contains only eight electrons in its outmost d-subshell.
Pt has a charge of +2 and it forms 4 bonds (each (en) group forms 2 bonds). It has $ds{p}^2$ hybridisation because parent central ion contains only eight electrons in its outmost d-subshell.
