Complete combustion of alkenes produces carbon dioxide and water, provided there is a plentiful supply of oxygen. Incomplete combustion of alkenes occurs where oxygen is limited and produces water ...

The researchers developed self-assembling small-molecule catalysts containing the metal palladium that can cleave a bond ...

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.

Such extensions will include the use of more complex ketones and alkenes for the simultaneous generation and control of multiple stereocenters. They focus upon the development of new methodology ...

(B) This is the structure of oleic acid, an 18-carbon unsaturated fat. The carbons of the alkene functional group, the site of unsaturation, are in the rounded rectangle. Since there is only one ...
