Which one of the following is expected to exhibit optical isomerism?(...
Cis-[Co(en)2Cl2] is expected to exhibit optical isomerism.
Explanation:
Optical isomerism occurs when a compound has a chiral center, which is an atom that is attached to four different groups or ligands. In order for a compound to exhibit optical isomerism, it must have at least one chiral center.
In cis-[Co(en)2Cl2], the complex is composed of a central cobalt atom (Co) coordinated to two ethylenediamine (en) ligands and two chloride (Cl) ligands. The ethylenediamine ligands are chelating, meaning they bond to the metal ion through two donor atoms. The chiral centers in this complex are the two nitrogen atoms in each ethylenediamine ligand.
In cis-[Co(en)2Cl2], the two ethylenediamine ligands are on the same side of the central cobalt atom. This arrangement creates a chiral center at the cobalt atom because the two nitrogen atoms in the ethylenediamine ligands are bonded to different ligands (Cl and en). This chiral center gives rise to optical isomerism.
On the other hand, in trans-[Co(en)2Cl2], the two ethylenediamine ligands are on opposite sides of the central cobalt atom. This arrangement does not create a chiral center at the cobalt atom because the two nitrogen atoms in the ethylenediamine ligands are bonded to the same ligands (Cl and en). Therefore, trans-[Co(en)2Cl2] does not exhibit optical isomerism.
Hence, the correct answer is option 'C' - cis-[Co(en)2Cl2].
