Question

A complex ion is a charged species consisting of a metal ion surrounded by ______and a coordination compound is a species consisting of complex ion surrounded by ______The oxidation and the coordination numbers of Cr in [Cr(en)_2(CN)_2]Cl respectively are: _____and ______ The predicted formula of the coordination compound formed by Pd^+2 (coordination number = 4) and the ligands: OH^-, H_2O, and Cl^- is: (no counter ion): ______ Among the complexes: [Cu(CN)_3^]^2--, [Zn(H_2O)_6]^2+, [Mn(CN)_6]^2-, the complex that's paramagnetic is:______ the geometry and the hybridization of the complex: [Fe(CN)(H_2O)_2(C_2O_4)Cl] respectively are: ______and _____ the number of unpaired electrons (uparrow) in the high-spin state of [CrBr_6]^-3 complex is: _____

Explanation / Answer

Ans 1. a complex ion is a charged species consisting of a metal ion surrounded by ligands and a coordination compound is a species consisting of complex ion surrounded by counter ions.

ligands bind to the complex ion by sharing their lone pair of electrons and forming a covalent bond. Coordination compounds have complex ions surrounded by cations or anions to produce a compound with no net charge.
