(colorless) (purple) (colorless) (brown ppt.) Reaction of an alkene with aqueous potassium permanganate results in addition of two hydroxyl groups to each side of the double bond to form a glycol. To ...

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 ...

the second most abundant alkane in seeps. They characterized enzymes involved in the process and found that their reaction ...
