Question

The shape of $\left[PtC{l}_3\right(C_2{H}_4){]}^{-}$ and the hybridisation of $Pt$ respectively are:

• A. tetrahedral, $s{p}^3$
• B. trigonal pyramidal, $s{p}^3$
• C. square planar, $ds{p}^2$
• D. square planar, $d^{2}s{p}^3$

Answer 1

The correct option is C square planar, $ds{p}^2$

Zeise's salt: $\left[K\right[PtC{l}_3({\eta }^2-C_3{H}_4)]$ is a $\pi$-complex and square planar in structure with $ds{p}^2$ hybridisation.
