Explanation:
The given compound is [Co(en)3]3+, which contains three ethylenediamine (en) ligands coordinated to a cobalt (III) cation.
Stereoisomerism:
Stereoisomerism is a form of isomerism in which the connectivity of atoms is the same, but the arrangement of atoms in space is different. In other words, stereoisomers have the same molecular formula and connectivity but differ in the spatial arrangement of their atoms.
Chirality:
Chirality is a property of a molecule that is not superimposable on its mirror image. Chiral molecules exist as pairs of enantiomers, which are non-superimposable mirror images of each other.
Achirality:
Achiral molecules are those that do not have chirality or do not possess a non-superimposable mirror image.
Now, let's analyze the given compound [Co(en)3]3+ for its stereoisomerism and chirality.
Analysis:
The coordination geometry of the cobalt (III) cation in [Co(en)3]3+ is octahedral, with three ethylenediamine (en) ligands arranged in a trigonal prismatic fashion around the central cobalt atom.
Trigonal Prismatic Geometry:
In a trigonal prismatic geometry, the three ligands are arranged in a trigonal plane, while the other three ligands are arranged above and below this plane.
Possible Stereoisomers:
In [Co(en)3]3+, the three ethylenediamine (en) ligands can be arranged in different ways around the central cobalt atom, resulting in different stereoisomers.
Chiral Stereoisomers:
If the arrangement of ligands leads to a chiral molecule, then it will have two enantiomers (mirror image isomers). In this case, two chiral stereoisomers can be formed.
Achiral Stereoisomer:
If the arrangement of ligands leads to an achiral molecule, then it will not have a non-superimposable mirror image. In this case, one achiral stereoisomer can be formed.
Conclusion:
Therefore, the compound [Co(en)3]3+ can have two chiral stereoisomers (enantiomers) and one achiral stereoisomer. Thus, the correct answer is option B.
The given compound is [Co(en)3]3+, which contains three ethylenediamine (en) ligands coordinated to a cobalt (III) cation.
Stereoisomerism:
Stereoisomerism is a form of isomerism in which the connectivity of atoms is the same, but the arrangement of atoms in space is different. In other words, stereoisomers have the same molecular formula and connectivity but differ in the spatial arrangement of their atoms.
Chirality:

Achirality:
Achiral molecules are those that do not have chirality or do not possess a non-superimposable mirror image.
Now, let's analyze the given compound [Co(en)3]3+ for its stereoisomerism and chirality.
Analysis:
The coordination geometry of the cobalt (III) cation in [Co(en)3]3+ is octahedral, with three ethylenediamine (en) ligands arranged in a trigonal prismatic fashion around the central cobalt atom.
Trigonal Prismatic Geometry:
In a trigonal prismatic geometry, the three ligands are arranged in a trigonal plane, while the other three ligands are arranged above and below this plane.
Possible Stereoisomers:
In [Co(en)3]3+, the three ethylenediamine (en) ligands can be arranged in different ways around the central cobalt atom, resulting in different stereoisomers.
Chiral Stereoisomers:
If the arrangement of ligands leads to a chiral molecule, then it will have two enantiomers (mirror image isomers). In this case, two chiral stereoisomers can be formed.
Achiral Stereoisomer:
If the arrangement of ligands leads to an achiral molecule, then it will not have a non-superimposable mirror image. In this case, one achiral stereoisomer can be formed.
Conclusion:
Therefore, the compound [Co(en)3]3+ can have two chiral stereoisomers (enantiomers) and one achiral stereoisomer. Thus, the correct answer is option B.
