Which of the following facts about the complex [Cr(NH3)6]CI3 is wrong?...
The outer orbital electronic configuration of Cr is 3d3 4s°.
The orbital diagram is represented in the figure
Here,
indicates lone-pair of NH3 donated to Cr.(a) d2sp3-hybridisation , octahedral. Thus, correct.
(b) There are three unpaired electrons, hence paramagnetic Thus, correct.
(c) d2sp3-inner orbital complex , thus in correct.
(d) Due to ionisable Cl- ions, white precipitate with AgNO3, thus correct.

Which of the following facts about the complex [Cr(NH3)6]CI3 is wrong?...
Explanation:
Incorrect Statement:
The complex [Cr(NH3)6]Cl3 is not an outer orbital complex. It is an inner orbital complex.
Correct Statements:
- Hybridisation and Shape: The complex involves d2sp3 hybridisation, where the 4s, 3d, and two 4p orbitals of chromium combine to form six sp3d2 hybrid orbitals. These orbitals arrange themselves in an octahedral shape around the central chromium atom.
- Paramagnetic Nature: The complex is paramagnetic due to the presence of unpaired electrons in the d-orbitals of the chromium atom, making it attracted to a magnetic field.
- White Precipitate Formation: The complex does give a white precipitate with silver nitrate solution. This reaction is used to confirm the presence of the chloride ion in the complex.
In conclusion, the incorrect statement is that the complex [Cr(NH3)6]Cl3 is an outer orbital complex. It is actually an inner orbital complex due to the involvement of the d-orbitals of the central chromium atom.
