Which among the following is a correct formula of Pentammine aqua cobalt (III) iodide?
- A \(\left[\mathrm{Co}\left(\mathrm{NH}_{3}\right)_{5}\left(\mathrm{H}_{2} \mathrm{O}\right)\right] \mathrm{I}_{3}\)
- B \(\left[\mathrm{Co}\left(\mathrm{H}_{2} \mathrm{O}\right)\left(\mathrm{NH}_{3}\right)_{5} \mathrm{I}\right]\)
- C \(\left[\mathrm{Co}\left(\mathrm{NH}_{3}\right)_{5} \mathrm{I}\right] \mathrm{H}_{2} \mathrm{O}\)
- D \(\left[\mathrm{Co}\left(\mathrm{H}_{2} \mathrm{O}\right)\left(\mathrm{NH}_{3}\right)_{5}\right] \mathrm{I}\)
Answer & Solution
Correct Answer
(A) \(\left[\mathrm{Co}\left(\mathrm{NH}_{3}\right)_{5}\left(\mathrm{H}_{2} \mathrm{O}\right)\right] \mathrm{I}_{3}\)
Step-by-step Solution
Detailed explanation
Amine \(\left(\mathrm{NH}_{3}\right)\) and aqua \(\left(\mathrm{H}_{2} \mathrm{O}\right)\) are neutral ligands. Oxidation state of \(\mathrm{Co}\) is \(+3\). Hence correct formula is \(\left[\mathrm{Co}\left(\mathrm{NH}_{3}\right)_{5}\left(\mathrm{H}_{2} \mathrm{O}\right)\right] \mathrm{I}_{3}\)
