"Products with double bonds—called alkenes—can be extremely useful. However, sometimes a single bond instead of a double bond is desired." "We have discovered that in certain cases, reactivity ...

(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 ...

The carbons of the alkene functional group, the site of unsaturation, are in the rounded rectangle. Since there is only one double bond, oleic acid is an example of a monounsaturated fatty acid.
