A cis complex having EAN value 84 and having two type of achiral monodentate ligand, when two same type of ligands are replaced by one butylenediamine (bn) then which of the following property is changed.
Options:
Answer:
Solution:
Determine complex geometry: Platinum (, atomic number 78) with an EAN of 84 has a coordination number of 4 (), indicating a square planar geometry.
Initial state: Square planar complexes with achiral monodentate ligands possess a plane of symmetry, making them optically inactive (zero optical isomers).
Effect of substitution: Replacing two monodentate ligands with butylenediamine (bn)—which is an optically active, chiral bidentate ligand—breaks the molecular symmetry.
Final outcome: The introduction of this chiral ligand induces asymmetry, which changes the number of optical isomers from zero to a non-zero value.
