The cis/trans or E/Z isomers formed by alkenes aren't the only example of stereoisomers. To understand the second example of stereoisomers, it might be useful to start by considering a pair of hands. For all practical purposes, they contain the same "substituents" four fingers and one thumb on each hand. If you clap them ...

WebJan 23, 2024 · Fundamentals of Chirality. Stereoisomers are isomers that differ in spatial arrangement of atoms, rather than order of atomic connectivity. One of their most … WebStereoisomers having instability at a stereogenic center can react to produce stereochemically modified forms. 15–18 This can be triggered by an adjacent group that decreases stability at the chiral center. 15 An enantiomer can irreversibly ‘racemize’ and reach the racemic mixture at equilibrium. It can also ‘enantiomerize,’ or reversibly …
