transEZisomerit

transEZisomerit is a term that appears to be a neologism, likely combining elements from "trans" (referring to a trans isomer), "EZ" (often used in organic chemistry to denote stereochemistry based on priority rules, similar to cis-trans), and "isomerit" (a plural form, possibly from a language like Finnish for isomers). As such, it does not correspond to a formally recognized chemical concept or compound class in standard scientific literature.

In organic chemistry, isomers are molecules with the same molecular formula but different structural or spatial arrangements of atoms. Geometric isomerism, also known as cis-trans isomerism or E/Z isomerism, is a type of stereoisomerism where the isomers differ in the spatial arrangement of substituents around a double bond or in a ring. The E/Z nomenclature system is used when the cis-trans designation is ambiguous, assigning priorities to substituents based on atomic number using the Cahn-Ingold-Prelog priority rules. The 'E' (from German *entgegen*, meaning "opposite") configuration has the higher priority groups on opposite sides of the double bond, while the 'Z' (from German *zusammen*, meaning "together") configuration has them on the same side. The term transEZisomerit might hypothetically refer to a collection of isomers that exhibit both trans-like properties (meaning substituents are on opposite sides) and adhere to the E/Z assignment system, or perhaps a specific subset of E/Z isomers where the 'E' configuration is being emphasized alongside a 'trans' descriptor. However, without further context or a specific chemical structure, its precise meaning remains undefined within established chemical terminology.
