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 ...

Bromine water is an orange solution of bromine. It becomes colourless when it is shaken with an alkene. Alkenes can decolourise bromine water, but alkanes cannot. The slideshow shows this process.

The general formula for the alkanes is C n H 2n+2 (where n is the number of carbon atoms in the molecule). The table shows four alkanes, their molecular formulae, displayed formulae and structural ...

An unsolved challenge in catalysis is the efficient and selective functionalization of simple alkanes and plentiful hydrocarbon feedstocks. One promising approach since the late 1990’s is the use of ...

Three long-chain alkanes detected by Nasa’s Curiosity rover could be chemical biosignatures that point to a history of past ...

In a breakthrough discovery, researchers have found the largest organic compounds ever seen on Mars, offering new clues about whether life once existed on the Red Planet. Buried within a ...
