Which of the following options explains why [Co(NH 3 ) 6 ] 3+ is an inner orbital complex whereas [Ni(NH 3 ) 6 ] 2+ is an outer orbital complex?
Options
- ACo +3 has d 7 configuration i.e. leads to d 2 sp 3 hybridisation/inner orbital complex but on the other hand,
- B[Co(NH 3 ) 6 ] 3+ has a higher oxidation state than [Ni(NH 3 ) 6 ] 2+ , leading to inner orbital complex forma
- C[Co(NH 3 ) 6 ] 3+ has a higher coordination number, resulting in inner orbital complex formation, whereas [Ni(
- DThe presence of ammonia ligands in [Co(NH 3 ) 6 ] 3+ promotes inner orbital complex formation, while [Ni(NH 3
Correct answer
A. Co +3 has d 7 configuration i.e. leads to d 2 sp 3 hybridisation/inner orbital complex but on the other hand,
Step-by-step solution
Correct Option is : (A) Co +3 has d 7 configuration i.e. leads to d 2 sp 3 hybridisation/inner orbital complex but on the other hand, Ni +2 has a d 8 configuration which leads to sp 3 d 2 hybridisation/outer orbital complex.
