About Isomerism

Isomerism occurs when compounds have the same molecular formula but different atom arrangements or spatial orientations. The content includes chain, position, functional, metameric and tautomeric isomerism, along with geometrical and optical isomerism, including cis-trans forms, E/Z notation, chirality and enantiomers.
