Z isomer
editWhat about Z isomer? I guess it might be less stable, and useful. 2A02:168:F609:0:5F8:C25A:2F16:ECD5 (talk) 21:25, 27 June 2019 (UTC) Definitively expecting different physical and chemical properties. Is synthesis favouring one of the enantiomers?
- According to Honeywell datasheets, the Z isomer has a boiling point of nearly 10 Celsius, some 30 degrees higher than the E isomer (this article is mostly giving the properties of the E isomer; the title should really reflect this, or better the article should cover the differences) which generally makes it a poor refrigerant or propellant, at least in the range of normal room temperature applications; presumably as a result of this higher BP it also takes up about twice as much space. Most applications seem to use the pure E isomer for these reasons. — Preceding unsigned comment added by 77.97.28.77 (talk • contribs) 14:46, 25 July 2021 (UTC)

editI think the molecule is drawn wrong; that's not the trans isomer, it's the cis isomer. Not 'E', but 'Z'. I'll be happy for anyone to correct me)— Preceding unsigned comment added by MBCF (talk • contribs) 18:16, 7 September 2020 (UTC)
- The image is of the trans isomer; the higher priority substituents (F and CF_3) are on opposite sides of the double bond.— Preceding unsigned comment added by 77.97.28.77 (talk • contribs) 14:46, 25 July 2021 (UTC)
