An element ' \(X\) ' with the atomic number 13 forms a complex of the type \(\left[\mathrm{XCl}\left(\mathrm{H}_2 \mathrm{O}\right)_5\right]^{2+}\). The covalency and oxidation state of \(X\) in it are respectively
- A \(5,+2\)
- B \(6,+2\)
- C \(5,+3\)
- D \(6,+3\)
Answer & Solution
Correct Answer
(D) \(6,+3\)
Step-by-step Solution
Detailed explanation
Element ' \(X\) ' is forming a complex of the type \(\left[X \mathrm{Cl}\left(\mathrm{H}_2 \mathrm{O}\right)_5\right]^{2+}\). Total number of ligands attached to \(X\) is 6 (one \(\mathrm{Cl}\) and five \(\mathrm{H}_2 \mathrm{O}\) ). \(\mathrm{Cl}\) is a unidentate ligand with…
