The Cl−Co−ClCl - Co - Cl bond angle values in a fac- [Co( NH 3)3Cl3]\left[Co{\left({\text{ NH }}_{3}\right)}_{3}{Cl}_{3}\right] complex is/are:The Cl - Co - Cl bond angle values in a fac- [Co ( NH _ 3 ) _ 3 Cl _ 3 ] complex is/are:

Options

  1. A90°90 ° & 180°180 °
  2. B90°90 °
  3. C180°180 °
  4. D90°90 ° & 120°120 °

Correct answer

B. 90°90 °

Step-by-step solution

In facial isomer, three ClCl atoms present on one face of the octahedron. Similarly, three ammonia molecules are present on one face of the octahedron. All 3 same ligands have 90°90 ° bond angle between them.

The Cl - Co - Cl bond angle values in a fac- [Co ( NH _ 3 ) _ 3 Cl _ 3 ] complex is/are:

The Cl−Co−ClCl - Co - Cl bond angle in above octahedral complex is 90°90 °
