Answer:
Ethene (ethylene) is the most important organic chemical, by tonnage, that is manufactured. It is the building block for a vast range of chemicals from plastics to antifreeze solutions and solvents.
Explanation:
The principal uses of ethene are to produce:
a) polymers
poly(ethene)
ethylbenzene and hence phenylethene and poly(phenylethene)
chloroethene (vinyl chloride) and hence poly(chloroethene), i.e. poly(vinylchloride), PVC
ethylbenzene and hence phenylethene and poly(phenylethene) polystyrene
b) other chemicals
epoxyethane and hence the diols, such as ethane-1,2-diol
ethanol
