MCQ

Select correct statement about anionic part of Zeise’s salt, $K\left[ {Pt\left( {{\eta ^2} - {C_2}{H_4}} \right)C{l_3}} \right]$

A
$C=C$ bond is coplanar with $Pt$ and $3$ $Cl$ atoms.
B
oxidation state of $Pt$ is $+3$ .
✓
$HCH$ bond angle is not same as that in free ethylene molecule.
D
$Pt-Cl$ bond is not affected by synergic bonding between $Pt$ and $C_2H_4$

✓

Answer

Correct option: C.

$HCH$ bond angle is not same as that in free ethylene molecule.

c
Due to synergic bonding between $Pt$ and ethylene, $C_2H_4$ is distorted and bond angles change from free $C_2H_4$ .
