Which of the following types of isomerism is exhibited by [ Co ( NH ₃ )₅ ( NO ₂ ) ] ( NO ₃ )₂ i. Optical ii. Linkage iii. Ionization iv. Coordination
Options
- Aii, iii only
- Bi, ii, iii only
- Ci, iii only
- Dii, iv only
Correct answer
A. ii, iii only
Step-by-step solution
No optical isomerism is exhibited by the given complex as there is a plane of symmetry. Linkage isomers :- [ Co ( NH ₃ )₅ ( NO ₂ ) ]²⁺ and [ Co ( NH ₃ )₅( ONO ) ]²⁺ Ionization isomers:- [ Co ( NH ₃ )₅ ( NO ₂ ) ]²⁺ and [ Co ( NH ₃ )₅ ( NO ₃ ) ]⁺ For coordination isomerism, both, cationic and anionic entities are required.
