Chemistry - Coordination Chemistry Question with Solution | TestHub

CoCl₃.XNH₃ gives 1 mole of AgCl. So one Cl^– ion is outside the complex. So 2Cl^– and 4NH₃ satisfy coordination number 6.

From the given data the possible complex is

$\left[\text{Co}{\left({\text{NH}}_3\right)}_4{\text{Cl}}_2\right]\text{Cl}$

So $x \mathrm{i}\mathrm{s} 4$
