Select the correct statement for Zeise's salt :

Options

A. The C=C bond is present in same plane to the `PtCl_(3)` group
B. C-C bond length of ethylene is higher in complex than C-C bond length of ethylene in isolated condition
C. The formula f Zeise's salt is `[Fe(pi-C_(5)H_(5))_(2)]`
D. The formula of Zeise's salt is `K[PtCl_(3)(C_(2)(CN)_(4))]`

Answer

B

Explanation

Zeise’s salt `rarr"KIPt"Cl_(3) (C_(2)H_(4))], C_(2)H_(4)` is perpendicular to square plane of Pt-complex. Due to back bonding to `pi^(*)` of `C_(2)H_(4)` , C-C B.L.`uarr`
