The rapid disappearance of the amber color of the bromine at room temperature is characteristic of reaction with alkenes. (colorless) (purple) (colorless) (brown ppt.) Reaction of an alkene with ...

This causes a smoky flame. Alkenes have a functional group C=C – the part of the molecule that takes part in reactions. Alkanes, in contrast, do not have a functional group and are less reactive ...

Researchers from the Hong Kong Polytechnic University, alongside mainland collaborators, have uncovered an unexpected phenomenon: severe wintertime ozone (O₃) pollution in Lanzhou, China, driven ...

Using heavy water, the researchers could also selectively introduce deuterium atoms along with chlorine. The weightier hydrogen isotope is useful for probing reaction mechanisms, as well as studying ...
