WebIn organic chemistry, a ring flip (also known as a ring inversion or ring reversal) is the interconversion of cyclic conformers that have equivalent ring shapes (e.g., from a chair conformer to another chair conformer) that results in the exchange of nonequivalent substituent positions. [1] WebCis-trans isomerism, also known as geometric isomerism, is a type of stereoisomer resulting from double bonds or ring structures. These structures lock the molecule in either the cis or trans form and it cannot …
