Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A): The complex [Co(en)₃]Cl₃ is a homoleptic complex. Reason (R): The ligand ethane-1,2-diamine coordinates to the central metal atom through two nitrogen donor atoms. In the light of the above statements, choose the most appropriate answer from the options given below:

Step-by-step solution

Assertion (A) is correct because homoleptic complexes are those in which the central metal atom is bound to only one kind of donor group (ligand). In [Co(en)₃]Cl₃ , the only ligand present inside the coordination sphere is ethane-1,2-diamine (en). Reason (R) is also correct because ethane-1,2-diamine ( H₂NCH₂CH₂NH₂ ) is a didentate ligand that binds through two nitrogen donor atoms. However, Reason (R) is not the correct explanation for Assertion (A). The complex is homoleptic because it contains only one type of l
