Which among the following is a correct formula of Pentammine aqua cobalt (III) iodide?

Options

  1. A[ Co ( NH ₃ )₅ ( H ₂ O ) ] I ₃
  2. B[ Co ( H ₂ O ) ( NH ₃ )₅ I ]
  3. C[ Co ( NH ₃ )₅ I ] H ₂ O
  4. D[ Co ( H ₂ O ) ( NH ₃ )₅ ] I

Correct answer

A. [ Co ( NH ₃ )₅ ( H ₂ O ) ] I ₃

Step-by-step solution

Amine ( NH ₃ ) and aqua ( H ₂ O ) are neutral ligands. Oxidation state of Co is +3 . Hence correct formula is [ Co ( NH ₃ )₅ ( H ₂ O ) ] I ₃
