JEE Mains · Chemistry · STD 12 - 5. Co-ordination chemistry
The coordination numbers of \(Co\) and \(Al\) in \([Co(Cl)(en)_2]Cl\) and \(K_3[Al(C_2O_4)_3]\), respectively, are (en \(=\) ethane \(-1,2-\) diamine)
- A \(6\) and \(6\)
- B \(5\) and \(3\)
- C \(3\) and \(3\)
- D \(5\) and \(6\)
Answer & Solution
Correct Answer
(D) \(5\) and \(6\)
Step-by-step Solution
Detailed explanation
\(en\) and \(C_2 O_4^{2-}\) are a bidentate ligand. So coordination number of \([Co(Cl)(en)_2]Cl\) is \(5\) and \(K_3[Al(C_2O_4)_3]\) is \(6\)
