Isomers

Isomers are molecule with same molecular formula but different structure e.g. nbutane and iso butane.

There are 8 types of Isomers

• Constitutional-   different in order of connection of functional group
• Stereoisomers – different in order of arrangement of atoms in bonds in space
• Conformational or rotational – formed by rotation in bonds
• Configurational – interchange at room temperatures
• Enantiomers- optical isomers with non superimposed mirror image,
• Diastereomers- Can be defined as stereoisomers that is not enantiomer and not an mirror image
• Optical isomers – isomers with non superimposed 3D image
• Geometric isomers – isomers with different spatial position and restricted rotation.
