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

Propane dehydrogenation (PDH) reaction is a highly endothermic reaction, typically requiring temperatures above 600°C in conventional thermo-catalysis. However, elevated temperatures lead to ...

The molecules are known as alkanes, hydrocarbons that combine chains ... "There is evidence that liquid water existed in Gale crater for millions of years and probably much longer, which means ...

For more than a decade, a robotic explorer has been traveling across Mars, quietly collecting clues about a time when the Red ...

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 of the alkanes is \({C_n}{H_{2n + 2}}\). They are insoluble in water. The names, molecular formula and the structural formula of the first eight alkanes must be learned.

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 ...

A dilute solution of bromine is added to samples of heptane and cyclohexene. The bromination reactions and mechanisms are compared. UV light splits the bromine molecule into two reactive radicals, ...
