The $HCH$ bond angle is the same as that in a free ethylene molecule.

Vedclass · Answer

(C) In Zeise's salt,the ethylene molecule acts as an $\eta^2$-ligand.Due to the synergic bonding (back-donation from $Pt$ $d$-orbitals to the $\pi^*$ orbital of ethylene),the $C=C$ bond length increases and the hybridization of carbon atoms changes from $sp^2$ towards $sp^3$.Consequently,the ethylene molecule becomes distorted,and the $HCH$ bond angle decreases compared to that in a free ethylene molecule.Therefore,statement $C$ is correct.
