Chemistry - Coordination Chemistry Question with Solution | TestHub

(A) The Be complex with unsymmetrical ligands is tetrahedral and lacks a plane of symmetry due to the bulky, different substituents on the rings.

(B) The Pt complex is square planar, but the ligands themselves contain chiral centers (C atoms with four different groups), making the whole complex optically active.

(C) This Zn complex has a plane of symmetry (the plane containing Zn and the ligands) or the ligands are arranged such that they reflect into each other, making it achiral.

(D) This is a chiral-at-metal "piano-stool" complex; Fe is bonded to four different groups (${\eta }^5-C_5{H}_5$, CO, PPh₃, and COCH₃), so it has no plane of symmetry.
