Complex Ions: Transition metal ion form complex ions. Complex ions formed when ligands bond to central metal ion by coordinate bond. Ligands: Ligands are molecules or ions that donate lone pair of electrons to a central metal ion to form coordinate bond or dative...

Complex Ion Shapes
Shape depends on coordination number. Six Coordinate Complexes: If complex ion has coordination number of 6, gives octahedral shape so 90 bond angles around central metal ion. When MnSO4 is dissolved in water. Forms complex ion with octahedral shape. Learn these...
Cis- Trans Isomerism in Complex Ions
Stereoisomerism: Complex ions display two types of stereoisomerism: cis- trans isomerism AND optical isomerism. Cis- Trans Isomerism: Some square planar and octahedral show show cis- trans isomerism. In complex ion, no double bond needed to restrict rotation....
Optical Isomerism
Optical Isomerism only occurs in octahedral complexes containing two or more bidentate ligands. Optical isomers aka enantiomers are pair of non- superimposable mirror images of each other. Cis- isomers may also show optical isomerism such as above. In questions,...
Ligand Substitution and Precipitation
Ligand Substitution: A ligand substitution is a reaction in which one ligand in a complex ion is replaced by another ligand. Reactions of Aqueous Copper (II) Ions: When copper (II) sulphate is dissolved in water, pale blue complex ion formed [Cu(H2O)6] 2+ Ligand...
D Block Elements
D Block Elements: Looking at scandium to zinc of period 4 of d block. All d block are metallic, so high MP, shiny, conduct electricity and heat. The highest energy sub-shell is a d sub-shell. Electron Configuration: Electrons added to 3d orbitals from 1 to 10....
