Industrial importance of alkenes

An essay type documents about the industrial importance of Alkenes for OCR Chemistry B. The important bits are highlighted and it really helps with application Questions. I'm doing A2 Chemistry now and got an A at AS so stuff like this really does work! :)

Industrial importance of Alkenes

Alkenes are a homologous series with the aliphatic general formula CnH2n; they also have a
double bond within their structure which makes them unsaturated and more reactive then a
saturated compound. It is because of this that they are useful in many industrial…

The Hydrogen then bonds with the Carbocation leaving a saturated molecule- Ethane.




This changes some of the Physical properties of the vegetable oil, such as the Melting point, making
it partially solidify. This is because the number of C-C double bonds can help determine the melting
point…

For example, the Alkene in the diagram above is called Prop-1-ene, but when put under certain
conditions around other Monomer units of the same species, the Pi-bond will break down causing it
to bond with the surrounding monomer units creating PolyProp-1ene or just Polypropene.
Polypropene has many…

However, because of the very unreactive nature or saturated Polymers, they cause a lot of
environmental problems and a high amount of wastage. Polymers are non-biodegradable so they
won't break down for thousands of years, this creates unsightly land fill sites which will very soon be
too…

Biodegradable plastics break down as a result of bacteria and compostable plastics must break down
by biological processes to create CO2, H2O and other inorganic compounds.
