Question

Which of the following facts about the complex [Cr(NH₃)₆]Cl₃ is wrong? 

1) The complex involves d² sp³ hybridization and is octahedral in shape. 

2) The complex is paramagnetic. 

3) The complex is an outer orbital complex. 

4) The complex gives white precipitate with silver nitrate solution.

Answer 1

3) The complex is an outer orbital complex. 

[Cr (NH₃)₆] Cl₃ uses inner (n-1) d orbitals and hence an inner orbital complex involving d² sp³ hybridization (octahedral shape)
