Mar 01, 2019  · A novel Q 3 →Q 4 transformation has been discovered in the structural transformation from a new interrupted zeolite PKU-26 to a fully four-connected zeolite framework PKU-27 upon heating, which can improve the thermal stability of the framework by the condensation of the terminal -OH groups. A plausible mechanism of the structural transformation involving proton transfer, framework.

E–Z configuration, or the E–Z convention, is the IUPAC preferred method of describing the absolute stereochemistry of double bonds in organic chemistry.It is an extension of cis–trans isomer notation (which only describes relative stereochemistry) that can be used to describe double bonds having two, three or four substituents.

Chemistry is the scientific discipline involved with elements and compounds composed of atoms, molecules and ions: their composition, structure, properties, behavior and the changes they undergo during a reaction with other substances. In the scope of its subject, chemistry occupies an intermediate position between physics and biology. It is sometimes called the central science because it.

Recently, I have encountered a problem regarding organic chemistry ; specifically the orientation of alkenes with the display of E-Z isomerism. Furthermore, the problem is not about when a compound is named E or Z, but the problem is why some compounds cannot form this type of display? A decent example would be that but-2-ene forms E-Z isomerism.
