What is ionisation isomerism and optical isomerism...???
Answers
Isomers are molecules that have the same molecular formula but a different arrangement of atoms in space. If the arrangement in space makes the two isomers nonsuperimposable mirror images of each other, we call them optical isomers or enantiomers. An example is the amino acid alanine.
Ionisation isomerism is a type of structural isomerism found in co-ordination compound. In this type of isomerism, the two isomers are formed due to different possible ions formation in the solution but the ions must balance the charge of the complex.
The ionisation isomers differ in only that one ion is attached to central metal while the another is not attached to the central metal cation.
For ex: The two ionisation isomers are [CoBr(H2O)5]+Cl- and [CoCl(H2O)5]+Br-
Here, the two isomers differ in position of halide ions.
