NEET · Chemistry · STD 12 - 5. Co-ordination chemistry

Given below are two statements : Statement I : \(\left[\mathrm{Co}\left(\mathrm{NH}_3\right)_6\right]^{3+}\) is a homoleptic complex whereas \(\left[\mathrm{Co}\left(\mathrm{NH}_3\right)_4 \mathrm{Cl}_2\right]^{+}\)is a heteroleptic complex. Statement II : Complex \(\left[\mathrm{Co}\left(\mathrm{NH}_3\right)_6\right]^{3+}\) has only one kind of ligands but \(\left[\mathrm{Co}\left(\mathrm{NH}_3\right)_4 \mathrm{Cl}_2\right]^{+}\)has more than one kind of ligands. In the light of the above statements, choose the correct answer from the options given below.

  1. A  Both Statement \(I\) and Statement \(II\) are false
  2. B Statement \(I\) is true but Statement \(II\) is false
  3. C  Statement \(I\) is false but Statement \(II\) is true
  4. D Both Statement \(I\) and Statement \(II\) are true
Verified Solution

Answer & Solution

Correct Answer

(D) Both Statement \(I\) and Statement \(II\) are true

Step-by-step Solution

Detailed explanation

\(\left[\mathrm{Co}\left(\mathrm{NH}_3\right)_6\right]^{3+}\) is a homoleptic complex as only one type of ligands \(\left(\mathrm{NH}_3\right)\) is coordinated with \(\mathrm{Co}^{3+}\) ion. While \(\left[\mathrm{Co}\left(\mathrm{NH}_3\right)_4 \mathrm{Cl}_2\right]^{+}\)is a heteroleptic complex in which \(\mathrm{Co}^{3+}\) ion is ligated with more than one type of ligands, i.e., \(\mathrm{NH}_3\) and \(\mathrm{Cl}^{-}\).
