Which one of the following forms, with an excess of CN- (cyanide), a complex having coordination number two ?
Options
A.Cu+
B.Ag+
C.Ni2+
D.Al(OH)3
Solution
Among the given metal ions only Ag+ forms complex with CN- having co-ordination number 2.
Ag + 2CN- → [Ag(CN)2]-
Coordination number of metals is defined as the number of σ-bonds by which ligands are attached to the metal atom.
