Concept explainers
(a)
Interpretation:
To determine the formula and charge of nickel complex which contain four carbonyl molecules and two chloride ions.
Concept introduction:
Coordination compounds are those in which a transition metal atom is bonded to a ligand which can be neutral, cation or anion. The
A ligand is an atom or a group of atoms or an anion that has an unshared pair of electrons and thus it can act as a Lewis base. It can donate its pair of electrons to the metal atom to form a coordinate bond with the transition metal atom.
(b)
Interpretation:
To determine the formula and charge of nickel complex which contain two ethylene diamine molecules.
Concept introduction:
Coordination compounds are those in which a transition metal atom is bonded to a ligand which can be neutral, cation or anion. The transition metal element is enclosed within a bracket and a charge is present on the ion to balance the charge present on the ligands.

(c)
Interpretation:
To determine the formula and charge of nickel complex which contain two thiocynate molecules, two hydroxide ions and two ammonia molecules.

- Four different octahedral chromium coordination compounds exist that all have the same oxidation state for chromium and have H2O and Cl as the ligands and counterions. When 1 mole of each of the four compounds is dissolved in water, how many moles of silver chloride will precipitate upon addition of excess AgNO3?arrow_forwardWhat is the coordination number of the central metal atom in the following complexes?
