Vedclass · Answer

(C) . $K[PtCl_3(\pi-C_2H_4)]$ contains a square planar platinum center,which is correct.$B$. $[Co(NH_3)_3Cl_3]$ exists as $fac$ and $mer$ geometrical isomers,neither of which is optically active,so this is correct.$C$. $[Fe(EDTA)]^-$ is an octahedral complex where $EDTA$ is a hexadentate ligand,so the coordination number is $6$. However,$[Fe(EDTA)]^-$ is not optically active because it has a plane of symmetry. Thus,this statement is incorrect.$D$. $[Co(NH_3)_5NO_2]Cl$ gives $1$ mole of $AgCl$ precipitate,while $[Pt(NH_3)_4]Cl_2$ gives $2$ moles of $AgCl$ precipitate with $AgNO_3$. They can be differentiated,so this is correct.
